A child is sitting on a stationary skateboard with a pile of rocks which she throws in one direction in order to make the skateboard
travel in the opposite direction. If the rocks each have a mass of 0.90 kg and she can throw them with a speed of 12 m/s relative to
the ground, determine the number of rocks she must throw per minute in order to maintain a constant average speed against a 1.8 N
force of friction. (Note: because this is a rate, the answer may not be a whole number.)

- After a 70 kg person steps from a boat onto the shore, the boat moves away with a speed of 0.7 m/s with respect to the shore. If the same person steps from the shore onto the boat, the person and the boat move away from the shore with the speed of 0.5 m/s. Assume that the initial speed of the person with respect to the shore is the same in both cases and that the person is moving in a horizontal direction.

The resistive force exerted by air on the airplane has a magnitude of 4.0 x 104 N. By Newton’s third law, if the engines exert a force on the exhaust gases to expel them out of the back of the engine, the exhaust gases exert a force on the engines in the direction of the airplane’s travel. This force is called thrust, and the value of the thrust in this situation is 7.50 x 104 N. (a) Is the work done by the exhaust gases on the airplane during some time interval equal to the change in the airplane’s kinetic energy? Explain.
