An 1800-kg pile driver is used to drive a steel beam into the ground. The pile driver falls 4.00 m before coming into contact with the top of the beam, and it drives the beam 9.0 cm farther into the ground as it comes to rest. Using energy considerations, calculate the average force the beam exerts on the pile driver while the pile driver is brought to rest. ________ n A 66.0 kg base runner begins his slide into second base when he is moving at a speed of 3.9 m/s. The coefficient of friction between his clothes and Earth is 0.70. He slides so that his speed is zero just as he reaches the base. (a) How much mechanical energy is lost due to friction acting on the runner? ________ J (b) How far does he slide? ________ m
