An engine pumps water continuously through a hose. Water leaves the hose with a velocity v and m is the mass per unit length of the water jet. What is the rate at which kinetic energy is imparted to water?
- \(\frac{1}{2} m v^{3}\)
- \(m v^{3}\)
- \(\frac{1}{2} m v^{2}\)
- \(\frac{1}{2} m^{2} v^{2}\)
Answer
(A) 1 2 m v^ 3
