A jet of water flowing from a hose at 15 m/s is directed against a wall.If the mass flow in the fluid stream is 4.3 kg/s,what force is the water applying to the wall if backsplash is negligible?
A) 30 N
B) 40 N
C) 65 N
D) 127 N

The force exerted by the water on the wall can be calculated using the formula F = Δp/Δt = m * v, where m is the mass flow rate and v is the velocity. Here, F = 4.3 kg/s * 15 m/s = 64.5 N, which rounds to 65 N.
