A horizontal spring with spring constant 150 N/m extends outward from a rigid wall. A 200 kg k g bumper car, including the mass of the occupant, hits the end of the spring at a speed of 0.50 m/s. By how much has the car’s kinetic energy changed at the instant the spring has maximum compression?
How much work does the spring do on the car from the moment of impact until the spring has maximum compression?
What is the maximum compression of the spring?

The rearrangement of particles in a physical change. hope this

When someone eats food

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
