Question

When its 75-kW (100-hp) engine is generating full power, a small single engine airplane with
mass 700 kg gains altitude at a rate of 2.5 m/s (150 m/min, or 500 ft/min). What fraction of the
engine power is being used to make the airplane climb (the rest is used to overcome drag and
friction)?

You are out on a nice bike ride in the mountains. You and the bicycle together have a mass of 83 kg. Up ahead, there is a huge hill to climb. You stop and drink some water and start to climb. The climb is very hard work. You entertain yourself with your nifty bike computer, which is reporting a power output of 400.0 W! At the end, you've climbed 128 m vertically in 4 minutes and 32 seconds! a) Assuming your power output was constant, how much work did you do during your climb? b) What is the energy transfer equation during this climb? c) Assuming your power output was constant, and no energy was lost, what was your final kinetic energy (remember you started off at rest?

You push on a box of 10kg with a force F = (20i −10j )N. It moves on a rough surface (uc = 0.1) over 2 m. The crate is initially stationary. Can you calculate the speed of the crate after 2 m, using the kinetic energy theorem?
A 3 kg block is sliding across a horizontal surface. The initial speed of the block is 4 m/s, but because of friction the block’s speed will decrease at a constant rate (i.e., constant acceleration) until the block finally comes to a stop after sliding 8 m. What is the average power (in W) supplied by friction as the block slows to a stop?
When an automobile moves with constant speed down a highway, most of the power developed by the engine is used to compensate for the mechanical energy loss due to frictional forces exerted on the car by the air and the road. If the power developed by the engine is 195 hp, estimate the total friction force acting on the car when it is moving at a speed of 30 m/s. One horsepower equals 746 W.
