Problem drops of rain fall perpendicular to the roof of a, Ask an Expert

Academics

Problem: Drops of rain fall perpendicular to the roof of a parked car during a rainstorm. The drops strike the roof with a speed of 16 m/s, and the mass of rain per second striking the roof is 0.049 kg/s.

Part A: Assuming the drops come to rest after striking the roof, find the average force exerted by the rain on the roof.

Magnitude:_______________________N

I need help to find the average force exerted by the rain on the roof.
