Force due to momentum transfer

Hail bounces off the roof of the car with a velocity of +15 m/s. Ignoring the weight of the hailstones, what is the force exerted by the hail on the roof.

Solution Preview

Let's assume that the hailstones reflect off the roof elastically, so that the change in vertical velocity is 30 meters/second. Suppose that during the hailstorm the mass flux of the hail is J.

J is the mass per square meter per second that is raining down. If the ...
