5. A .012 kg block of wood sits on a frictionless incline on a spring, as shown in the diagram below. The block is pushed down, so it compreshes the spring by Ax = 0.075 m, and is then released. What is the velocity of the block when it passes its original position
on its way up the incline? 0 = 28°. The spring constant is 220 N/m.

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
