During a storm, rain comes straight down with an initial velocity of vi=-15 m/s and hits the roof of a car perpendicularly (see Figure below). The mass of rain per second that strikes the car roof is 0.061 kg/s. Assuming that the rain comes to rest upon striking the car (final velocity, vf = 0 m/s), find the average force exerted by the rain on the roof. Vf value is not included as reference for significant figures for the final answer Tip: Be careful with the direction of the final answer (force exerted by raindrop) :)   Round your answer to 2 significant figures
