Question

a hailstone of mass 4.67 x10^-3 kg falls vertically at constant speed under influence of gravity and air resistance. What is the work done on the raindrop by the gravitational force and air resistance in joules if it falls for about 1.00 km? (present your answer in this form; x.xxx, x.xxx)

Answer 1

$$W_g=mgh=(4.67\cdot10^{-3})(9.8)(1000)=45.8\ J$$

$$W_a=-W_g=-45.8\ J$$
