a plane travels 360 km in 3 hours. what is its velocity
The velocity of the plane is 120 km/hr.
How would you define velocity?Velocity is the pace at which an object's location is changing as perceived from a particular point of view and as measured by a certain unit of time (for example, 60 km/h northbound). Velocity is the direction at which an object is traveling. Velocity is a fundamental concept in kinematics, the branch of classical mechanics that deals with the motion of bodies. In order to be defined, the physical vector quantity known as velocity needs to have both a magnitude and a direction. Speed is a coherent derived unit whose quantity is measured in metres per second (m/s or m/s1) in the SI. Speed is the scalar absolute value (magnitude) of velocity (metric system). As opposed to "5 meters per second east," which is a vector, "5 meters per second," for instance, is a scalar.
Distance traveled = 360 km
Time taken = 3 hours
Hence, velocity = 360/3 = 120 kmph
Thus, the velocity of the plane is 120 km/hr.

The table shows mass and weight data of some common items.
Based on the data, which conclusion is valid regarding the relationship between the force of gravity, mass, and weight?
The weight of an object depends on the force of gravity of the planet, but the mass does not.
Neither the mass nor the weight of an object depends on the force of gravity.
The mass of an object depends on the force of gravity of the planet, but the weight does not.
Both the mass and the weight of an object depend on the force of gravity.
An increase in the distance between the objects causes a greater change in the gravitational force than the same increase in mass. It depends on the object's mass and acceleration due to gravity.
Mass is an intrinsic unchanging property. Weight is a force and it depends on gravitational force. This force is directly proportional to mass the more mass the object has the stronger the force of gravity will be. Because of this, it turns out that gravity does not matter when we compare the distance traveled by objects with different masses. The important part of the force is air resistance also called drag.
The slope of the graph is the relationship between weight and mass. The slope tells how many newtons of weight pull down on each kilogram of mass. Mass is the measure of the amount of matter in an object. This is an immutable property inherent in the body. Mass cannot be destroyed or created. Weight is the production of mass and acceleration due to gravity.

mg x sin A calculates the force pushing the mass down the hill. Additionally, this force has the same formula: m x a, where an is the actual acceleration in the plane. By dividing the difference between the two speeds by the provided time, or 5.07 m/s - 1.31 m/s / 1.73 s = 4.34 m/s2, the acceleration a may be calculated.

A ball rolls down a ramp for 15 seconds. If the initial velocity of the ball was 2.1 m/sec and the final velocity
was 7.3 m/sec, what was the acceleration of the ball?
Answer: a=.347
Explanation: Acceleration can be calculated by subtracting the initial velocity (2.1 m/s) from the final velocity (7.3) and dividing the difference by the time (15s).
[tex]\frac{7.3-2.1}{15} = .347[/tex]
a train slows down as it rounds a sharp horizontal turn, going from 96.0 km/h to 58.0 km/h in the 16.0 s that it takes to round the bend. the radius of the curve is 120 m. compute the acceleration at the moment the train speed reaches 58.0 km/h. assume the train continues to slow down at this time at the same rate.
The acceleration vector will be the vector sum of the tangential and radial acceleration components because the train is changing both its speed and direction.
Since the train is altering both its speed and direction, the vector sum of the tangential and radial acceleration components will represent the acceleration vector.
The radius of curve and the train's speed can be used to calculate the tangential acceleration, while the elapsed time and changing speed can be used to calculate the radial acceleration.
Let's first convert the speed measurements from km/h to m/s:
v I = 90.0 km/h
= (90.0 km/h) (10 3 m/km) (1 hour and 36 minutes)
= 25.0
m/s v f = 50.0 km/h
= (50.0 km/h) (10 3 m/km) (1 hour and 36 minutes)
= 13.9 m/s
Backwards, the tangential acceleration is equal to a t = t v = 15.0s (13.9 m/s 25.0 m/s = 0.741 m/s 2), and the radial acceleration is equal to a r = r v 2.
Consequently, an is equal to 1.48 m/s 2 inward and 29.9 0 backward.

Look at the energy bar graph on the left. The total energy does not move, as it shows the maximum energy used or stored at any given instant. However, the potential energy and kinetic energy are constantly changing. Why?
The potential energy and kinetic energy are constantly changing because of law of energy conservation as the kinetic energy is constantly being converted into potential energy and vice versa.
What is the law of conservation of energy?
The law of conservation of energy states that energy can neither be created nor destroyed but can be converted from one form to another.
The total mechanical energy of any system is made up of kinetic energy and potential energy.
The kinetic energy is the energy of the object due to its motion while the potential energy is the energy of the object due to its height above the ground.
Based on the law of conservation of energy, the kinetic energy of an object can be converted into potential energy and from potential energy to kinetic energy.

a crane lifts a 425 kg steel beam vertically a distance of 79.0 m . how much work does the crane do on the beam if the beam accelerates upward at 1.60 m/s2 ? neglect frictional forces.
The crane does increase the kinetic and potential energy of the beam: W=ΔK+ΔU. Potential energy fluctuates with height while kinetic energy changes with speed W=mΔv2/2+mgΔh.
We should figure out v before moving on. We are aware that the beam is moving 95 meters away at an acceleration of 1.8 text m/s/s. Assuming that the acceleration is uniform and that the initial velocity was 0 m/s.
v2f=v2i+2aΔx
v2f=(0 m/s)
2+2(1.8 m/s2)(95 m) (95 m)
v2f=342 m2/s2 (saving one additional sign. for calculations in the future)
vf=18.5 m/s
Now that we are aware of acceleration vf and v, we may proceed to calculate W.
W=mΔv22+mgΔh
W=m(Δv22+gΔh)
W = 425 kg((18.5 m/s)22+(9.81 m/s2)(95 m))+(9.81 m/s2)
W=(425 kg)(171 + 932 m2/s2)

W=469000 J→4.7×105 J

Newton's first law states that unless a force is applied to a body, it will stay in either its resting or uniformly moving condition along a straight path. According to the second law, when an external force applies on a body, the body accelerates (changes velocity) in the force's direction.
