A body of mass 0.25 kg is projected with muzzle velocity `100 ms^(-1)` from a tank of mass 100 kg. What is the recoil velocity of the tank?

Options

A. `5 ms^(-1)`
B. `25 ms^(-1)`
C. `0.5 ms^(-10)`
D. `0.25 ms^(-1)`

Answer

D

Explanation

Using law of conservation of momentum, we get
`100 xx v=0.25xx100 implies v=0.25 ms^(-1)`
