A bicyclist is coasting straight down a hill at a constant speed. The mass of the rider and bicycle is 89.0 kg, and the hill is inclined at 13.0° with respect to the horizontal. Air resistance opposes the motion of the cyclist. Later, the bicyclist climbs the same hill at the same constant speed. How much force (directed parallel to the hill) must be applied to the bicycle in order for the bicyclist to climb the hill? Number Units

A bicyclist maintains a constant speed of 4.00 m/s up a hill that is inclined at 10.0 degrees with the horizontal. Calculate the work done by the person and the work done by gravity if the bicycle moves a distance of 19.0 m up the hill. The combined mass of the rider and the bike is 88.0 kg. 1) Calculate the work done by gravity. 2) Calculate the work done by the person.

A driver coasts down a hill 200 m high with initial speed vo 35 m/s. The road has friction that results in a negative work -1.7 x 10° J. The effect of this is that the total initial energy is reduced by this amount by the time the car reaches the bottom of the hill. Calculate the speed of the car when it reaches the bottom of the hill. The mass of driver and passenger is 1750 kg 59.3 m/s...
