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.© BrainMass Inc. brainmass.com July 19, 2018, 6:54 pm ad1c9bdddf
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 ...
A detailed solution is given.
