A person in good physical condition can put out 100 W of useful power for several hours at a stretch, perhaps by pedaling a mechanism that drives an electric generator. Neglecting any problems of generator efficiency and practical considerations such as resting time: (a) How many people ‘would it take to nm a 4.O0-kW electric clothes dryer? (b) How many people would it take to replace a large electric power plant that generates 800 MW?

A 2 kg Box slides down an inclined plane. It has an incline of 1.09956 radians and coefficient of kinetic friction of 0.49. What is the final speed of the Box if it started at rest and the change in height is 2.4 m?
A 2.0kg disk is able to move on a straight, level track with negligible friction. With the disk initially at rest, ahorizontal force is applied to the disk. The force is measured as a function of the disk’s displacement, and thedata are shown in the graph above. When the disk’s displacement is 2.0m, what is the speed of the disk?
