Q1. A 2.19 kg block initially at rest is pulled to the right along a horizontal surface by a constant, horizontal force of 16.1 N. The coefficient of kinetic friction is 0.145.
The acceleration of gravity is 9.8 m/s2.
Find the speed of the block after it has moved 3.35 m.
Q2. A 75 kg parachutist descends through a vertical height of 310 m with constant speed. Find the increase in entropy produced by the parachutist, assuming the air temperature is 21°C.
