During a hailstorm, hailstones with an average mass of 2g and a speed of 15m/s fall vertically down and strike a winshield angled at 45 degrees and bounce off at the same speed horizontally. The area of the window is .5m2 What is the average pressure they exert on the window?
The Attempt at a Solution
So far this is what i've worked out:
Pressure = Force/Area
Force = ma but since there is no loss in velocity then that means that a=0 and the stones exert no force on the window?
