The speed of the ball 0.60 seconds after it is released is 6.8 m/s.
Newton's law of motion is given by:
v = u + gt
where v is the final velocity, u is the initial velocity, g is the acceleration due to gravity and t is the time.
Given that:
u = 0.8 m/s, g = 10 m/s², t = 0.6s. Hence:
v = 0.8 + 10(0.6)
v = 6.8 m/s
Therefore the speed of the ball 0.60 seconds after it is released is 6.8 m/s.

Explanation: I took the test
The pre-Columbian civilization that was the earliest to exist is Maya. The correct option is c.
What is civilization?A society is a diverse culture in which large numbers of people exchange similar characteristics. Historians have established the essential characteristics of civilizations. Six of the most important characteristics are cities, democracy, faith, the social system, writing, and art.
The pre-Columbian civilizations were extraordinary advances in human society and culture, ranking alongside Egypt, Mesopotamia, and China.
It was significant because it acknowledged how diverse and complex these early civilizations were, as well as how they continue to influence us after hundreds of years. The Columbian civilization in Latin America in this case includes the Aztec, Maya, and Inca.
Therefore, the correct option is c. Maya.

a box contains 10 equal-sized balls, numbered 1 to 10. two balls are drawn at random simultaneously. what is the probability that the numbers on the two balls will differ by more than 2?
The probability that the two balls are chosen will differ by more than 2 is 43/45
Probability is the likelihood or chance that an event will occur.
If a box contains 10 equal-sized balls and 2 balls are chosen at random from the box, the total outcome will be expressed as:
[tex]10C_2=\frac{10!}{(10-2)!2!}\\ 10C_2=\frac{10!}{8!2!}\\10C_2=\frac{10\times 9 \times 8!!}{8!2!}\\10C2=\frac{90}{2} =45 ways[/tex]
If the number on the two balls chosen will differ by less than or equal to 2, the expected outcomes are (1, 2), (1, 3) that is 2 outcomes
The probability that the two balls are chosen will differ by less than or equal to 2 is 2/45
The probability that the two balls are chosen will differ by more than 2 is 1 - 2/45 = 43/45

A community pool that is shaped like a regular pentagon needs a new cover for the winter months. The radius of the pool is 20.10 ft. The pool is 23.62 ft on each side. To the nearest square foot, what is the area of the pool that needs to be covered? 192 ft2 960 ft2 1,921 ft2 3,842 ft2
Answer:
B. 960 ft^2
Explanation:
edge says trust me
Based on the calculations, the area of this pentagonal pool that needs to be covered is equal to: B. 960 ft².
Given the following data:
Radius of pool = 20.10 ft.
Side length of pool = 23.62 ft.
How to calculate the area of the pool?Mathematically, the area of a regular pentagon can be calculated by using this formula:
A = ¹/₄√(5(5 + 2√5)a²)
Where:
a is side length.
Substituting the parameters into the formula, we have:
A = ¹/₄√(5(5 + 2√5)23.62²)
A = ¹/₄√(5(5 + 2√5)557.9044)
A = 959.86 ≈ 960 ft².

a 15.0 kg block is attached to a very light horizontal spring of force constant 575 n/m and is resting on a smooth horizontal table (figure 1). suddenly it is struck by a 3.00 kg stone traveling horizontally at 8.00 m/s to the right, whereupon the stone rebounds at 2.00 m/s horizontally to the left.
The instantaneous velocity of the 15 kg. mass just after collision can be found by the principle of linear momentum.
a) The speed of the 15 kg. just after collision is 2 m/s.
b) The type of collision is inelastic collision
c) The compression of the spring is approximately 0.323 m.
Reasons:
The given parameters are;
Mass of the block attached to the spring, m₁ = 15.0 kg
Force constant of the spring, K = 575 N/m
Mass of the stone that strikes the block, m₂ = 3.00 kg
Speed of the stone, v₂ = 8.00 m/s
Speed with which the stone rebounds, v₃ = 2.00 m/s
a) The total initial momentum = 3 kg. × 8 m/s = 24 kg·m/s
The final momentum, just after collision = 3 × (-2) kg·m/s + 15 kg ×v₁
By conservation of momentum, we have;
24 kg·m/s = 3 × (-2) kg·m/s + 15 kg ×v₁
[tex]v_1 = \dfrac{24 \, kg \cdot m/s + 6 \, kg \cdot m/s}{15 \, kg} = 2 \, m/s[/tex]
The speed of the 15 kg. just after collision, v₁ = 2 m/s.
b) A collision is elastic when the kinetic energy of the collision is conserved
The initial kinetic energy, K.E.₁ = 0.5 × 3 kg. ×(8 m/s)² = 96 J
The sum of the final kinetic energy are;
0.5 × 3 kg. × (2 m/s)² + 0.5 × 15 kg × (2 m/s)² = 36 J
The initial kinetic energy ≠ The final kinetic energy
Therefore, the collision is not elastic
(c) The kinetic energy given by the block = The elastic potential energy gained by the spring
Kinetic energy of the block, K.E. = 0.5 × 15 kg × (2 m/s)² = 30 J
Elastic energy gained by the block = 0.5 × K × x² = 0.5 × 575 N/m × x²
Therefore;
0.5 × 575 N/m × x² = 30 J
[tex]x^2 = \dfrac{30 \, J}{0.5 \times 575 \, N/m} = \dfrac{12}{115} \, m^2[/tex]
[tex]x = 2 \cdot \sqrt{\dfrac{3}{115} } \approx 0.323[/tex]
The compression of the spring, x ≈ 0.323 m.

Michael and Jacob are standing on two docks that are 20 miles apart. They are watching a ship that is out in the ocean. The angle between the dock and the line connecting Michael and the ship is 48°, and the angle between the other dock and the line connecting Jacob and the ship is 37°. A triangle with points labeled Ship, Jacob, and Michael is shown. The length between Michael and Jacob is 20 miles. The angle between the ship, Michael, and Jacob is 48 degrees. The angle between the ship, Jacob, and Michael is 37 degrees. If the ship can travel to either dock, which dock would be closest? Explain your answer. Michael’s dock would be closer because the angle opposite is smaller. Jacob’s dock would be closer because the angle opposite is smaller. Michael’s dock would be closer because the docks are 20 miles apart. Jacob’s dock would be closer because the docks are 20 miles apart.
Answer:

Explanation:
If the ship can travel to either dock, the dock that would be closest is Michael’s dock would be closed because the angle opposite is smaller. The correct option is A.)
What are triangle inequalities?The triangle inequality theorem explains the connection between a triangle's three sides. This theorem states that for any triangle, the sum of the lengths of the first two sides is always greater than the length of the third side.
The vertices must be colinear, which means that the three sides form a line segment rather than a triangle if the length of one side equals the total of lengths of the other two sides. The triangle inequality is what we refer to here. Any triangle side must be shorter than the sum of the other two sides.
Therefore, the correct option is A.) Michael’s dock would be closed because the angle opposite is smaller.
