24) A heavy sled and a light sled, both moving horizontally with the same speed, suddenly slide onto a rough patch of snow and eventually come to a stop. The coefficient of kinetic friction between the sleds and the rough snow is the same for both of them. Which of the following statements about these sleds are correct? (There could be more than one correct choice.)
A) Both sleds will slide the same distance on the rough snow before stopping.
B) The heavy sled will slide farther on the rough snow than the light sled.
C) The light sled will slide farther on the rough snow than the heavy sled.
D) The friction from the snow will do more negative work on the heavy sled than on the light sled.
E) The friction from the snow will do the same amount of work on both sleds.

In the sport of parasailing, a person is attached to a rope being pulled by a boat while hanging from a parachute-like sail. a rider is towed at a constant speed by a rope that is at an angle of 15 β from horizontal. the tension in the rope is 1900 n. the force of the sail on the rider is 30β from horizontal. what is the weight of the rider? express your answer with the appropriate units.

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.
