water leaves a hose at a rate of 1.5kg/s with a speed of 20m/s and is aimed at the side of a car, which stops it (splashing back is ignored). what is the force exerted by the water on the car?

Answer 1

force=mass*acceleration

so consder in one second...

force=1.5kg*(changevelocity/time)

and you have the change in velocity per second.

acceleration= -20m/s^2

Answer 2

water leaves a at a rate of 1.5 kg m/s with speed of 20m/s and is aimed at the side od the car which stop it what is the force exerted by the water on the car
