Here are a few practice problems on the work-energy theorem for you to work on:
-
A 2 kg object is initially at rest on a frictionless surface. A force of 10 N is applied to the object for a distance of 5 meters. Calculate the final velocity of the object.
-
A 500 g object is dropped from a height of 10 meters. Calculate the velocity of the object just before it hits the ground, assuming no air resistance.
-
A 1 kg object is pulled along a rough surface with a force of 5 N at an angle of 30 degrees above the horizontal. If the object moves a distance of 8 meters, calculate the work done on the object.
Remember to apply the work-energy theorem to solve these problems!
