Question
A large cylindrical tank of cross-sectional area 1m2 is filled with water. It has a small hole at a height of 1 m from the bottom. A movable postilion of mass 5 kg is fitted on the top of the tank such that it can side in the tank freely. A load of 45 kg is applied on the top of water by piston, as shown in figure. The value of v when piston is 7m above the bottom is (g = 10 m/s2)
Options
A.
m/s
m/sB.10 m/s
C.1 m/s
D.11 m/s
ρv2 = ρgh + 
⇒ 
= 
= 11m/sMore Momentum and Collision Questions
