Drops of rain fall perpendicular to the roof of a parkedcar during a rainstorm. The drops strike the roof with a speedof 12 m/s, and the mass of rain per second striking the roofis 0.035 kg/s. (a) Assuming the drops come to rest after strikingthe roof, find the average force exerted by the rain on theroof. (b) If hailstones having the same mass as the raindropsfall on the roof at the same rate and with the same speed, howwould the average force on the roof compare to that found inpart (a)?

During a storm, rain comes straight down at a rate of 46.8 kph and perpendicularly hits the roof of a vehicle. Assuming the mass of rain per second that strikes the vehicle's roof is 270 kg/hr. Considering that the rain comes to rest upon striking the car, find the average force exerted by the vehicle's roof on that rain.
