Water pouring from a broken pipe lands on a flat roof. The water is moving at 5.0 m s−1 when it strikes the roof.

Water pouring from a broken pipe lands on a flat roof. The water is moving at 5.0 m s−1 when it strikes the roof. The water hits the roof at a rate of 10 kg s−1. Calculate the force of the water hitting the roof. (Assume that the water does not bounce as it hits the roof. If it did bounce, would your answer be greater or smaller?)
