A car wash nozzle directs a steady stream of water at 2.0 kg/s,with a speed of 30 m/s,against a car window.What force does the water exert on the glass? Assume the water does not splash back.

Question

Quizplus · Accepted Answer

The force exerted by the water on the glass can be calculated using the formula F = Δp/Δt = m*v, where m is the mass flow rate (2.0 kg/s) and v is the velocity (30 m/s). Thus, F = 2.0 kg/s * 30 m/s = 60 N.
