An engine pumps water continuously through a hole. Speed with which water passes through the hole nozzle is v and k is the mass per unit length of the water jet as it leaves the nozzle. Find the rate at which kinetic energy is being imparted to the water.
- \(\frac{1}{2} k v^{2}\)
- \(\frac{1}{2} k v^{3}\)
- \(\frac{v^{2}}{2 k}\)
- \(\frac{y^{3}}{2 k}\)
Answer
(B) 1 2 k v^ 3
