3. A box, initially at rest, is placed on the top of the frictionless incline shown. 6 m A) Using a free body diagram and Newton's second law, find the box's acceleration in m/s². 8 m B) Use the constant acceleration equations to find the speed of the box when in reaches the bottom of the incline. C) Find the work done by the constant net force on the box as it slides from the top of the incline to the bottom. Use the work-kinetic energy theorem to find the speed of the box when it reaches the bottom of the incline and check that your answer agrees with B).
