Problem 65. A ball of mass 0.2 kg is thrown straight up in the air with a speed of 10 m/s. Find the speed of the ballwhen it returns to the level from which it was thrown if air resistance does -1J of work on the ball during its flight.Problem 66. As a person pushes a box of mass 2 kg across level ground, the speed of the block increases from 1 m/s to 5m/s. Find the work done by the person on the box. Assume that no other forces do work on the box.
