Please read the problems carefully and answer them in the space provided. Write on the back of the page, if necessary. Partial credit will be given unless specified otherwise. A body of mass m slides a distance d along a horizontal surface with a coefficient of kinetic friction s. Determine how much work is done by gravity: mgd, zero, mgd, one cannot tell from the information provided, none of these is correct. A golf ball and a ping-pong ball are dropped from the same height in a vacuum chamber. When they have fallen halfway to the floor, they have the same: speed, potential energy, kinetic energy, momentum, speed, potential energy, kinetic energy, momentum. Santa and his new turbo-charged sled are heading due east. Santa"s airspeed indicator shows that the sled is moving at a speed of 370 km/h relative to the air.
