Hockey ball of mass 200 gram travelling at 10 metre per second is struck by hockey stick. So as to return it along its original path with a velocity at 5 metre per second calculate the magnitude of change of momentum occurred in the motion of the hockey Ball by the force applied by the hockey stick. ​

Answer:

3000gm/s

Explanation:

Mass = 200

v = 5

u = 10

Momentum = mass(v - u)

But because the ball is returning through the same path

Momentum = m(v + u)

Ft = 200 ( 5 + 10)

= 200 x 15

= 3000gm/s
