Question

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

Answer 1

F = v dm/dt
= 5 x 1 
= 5N

acceleration= a = F/m
= 5/2
= 2.5 ms⁻²

Answer 2

Answer:

Explanation:

Hope you understood this. This problem is done with the help of Newton law and find out the acceleration
