A block of metal weighing 2 kg is resting on a frictionless plane. It is struck by jet releasing water at the rate of 1kg/s and at a speed of 5m/s the initial acceleration of block is?
Using Newton’s second law of motion, i.e.
Where,
F= force
p = momentum
In the given question the water released by the jet applies force due to change in mass as the velocity is constant.
Given,
The velocity of water released by jet= v
change in mass of water released by jet = 
Now, this force exerted by the water released by the jet exerts force on the block of mass 2 kg
This force causes the block to accelerate
Let, a= initial acceleration of the block then using,
