Problem 4 Consider a motorcycle with a mass of 300.0 kg (including the rider) traveling at a constant speed 20.0 m/s. The force of air resistance depends on the speed of the object. Suppose that at 20.0 m/s, the air provides a constant force of 325 N, opposing the motion of the motorcycle. (a) Find the power needed from the motor to travel on level ground at 20.0 m/s, in units of Watts. (b) Find the power needed from the motor to go up a hill inclined at 5.00° with this same constant speed of 20.0 m/s.
