Answers
Answer:
A) y = 1.3x + 10
Explanation:
2 Points on the graph by using x and y values:
(0, 10) and (10, 23)
Slope:
m= (y2-y1)/(x2-x1)
m= (23 - 10)/(10 - 0)
m= 13/10
m = 1.3
Slope-intercept:
y - y1 = m(x - x1)
y - 10 = 1.3(x - 0)
y - 10 = 1.3x
y = 1.3x + 10

How does the mass of a wheelchair influence the force needed to move it?
Answers
Answer:
When mass is greater, the force needed must be greater keeping the acceleration of the wheel chair constant
Explanation:
[tex]force = mass \times acceleration \\ f \: \alpha \: m[/tex]
force is directly proportional to the mass

Which spring has more potential energy stored?
a) 1.0 N/m constant spring stretched 0.2 m.
b) 2.0 N/m constant spring stretched 0.2 m.
c) 1.0 N/m constant spring stretched 0.3 m.
d) 2.0 N/m constant spring stretched 0.3 m.
Answers
Work is done when spring is extended or compressed. Elastic potential energy is stored in the spring. Provided inelastic deformation has not happened, the work done is equal to the elastic potential energy stored.
Answer: c) 1.0 N/m constant spring stretched 0.3 m.
Explanation:
An object of mass 100kg is moving with a velocity of 5m/s. Calculate the kinetic energy of that object
Answers
Answer:
1250 J
Explanation:
KE = 1/2(100 kg)(5 m/s)^2
KE = 1250 J
V=5m|s
Required KE=?
Solution KE=1/2mv^2
=1/2 100kg(5m/s)^2
=50kg*25(m/s)^2
=1250J
A car is moving at 80km/h accelerates to pass a truck. Five seconds later the car is moving at 100km/h. What is the Acceleration of the car? Please show the equation, Ty.
Answers
Answer/Explanation:
Acceleration is the rate of change of the velocity of an object that is moving. This value is a result of all the forces that is acting on an object which is described by Newton's second law of motion. Calculation of such is straightforward, if we are given the final velocity, the initial velocity and the total time interval. We can just use the kinematic equations. Fortunately, we are given these values. So, we calculate as follows:
acceleration = v - v0 / t
acceleration = (80 mph - 50 mph) ( 1 h / 3600) / 5 s
acceleration = 1.67 x 10^-3 m / s^2
a = 27.78 m/s - 22.2 m/s ÷ 5 seconds
a = 1.116 m/s ²
*you needed to convert the km/h to m/s for proper evaluation, which is what i did*
