Question

hockey ball of mass 250 gram travelling at 15 metre per second struck by a hockey stick so as to return it along its original part with a velocity of 10 metre per second calculate the change in momentum occurred in the motion of the hockey Ball by the force applied by the hockey stick​

Answer 1

Answer:

This might help you.I couldn't find the time so I am skipping the second sub-question

Explanation:

M=250g = 0.250kg

U=15m/s

V= -10m/s

Change in momentum = m(V-U)

= 0.250(-10-15)

= 0.250× - 25

= - 6.25kgm/s
