Find the magnitude of the force exerted by the hail on roof

Reference no: EM13538586

The hail comes straight down at a mass rate of m/?t=0.069 kg/s and an initial velocity of v0= -15 m/s. Suppose that the hail described there bounces off the roof of the car with a velocity of +12.1 m/s. Ignoring the weight of the hailstones, calculate the magnitude of the force exerted by the hail on the roof.
