Question

A hockey ball of mass 200 g travelling at 10 m s-¹ is struck by a hockey stick so as to return it along its original path with a velocity at 5 m s-¹ calculatChe Chingnu g foto do thagtlaga Rip hynahyraga thagtlko amtae the magnitude of change of momemtum occurred in the motion of the hockey ball by the force applied by the hockey stick

Answer 1

Answer:

change in momentum = mv-mu

u=10m/S

v=5m/S

m=200g

mv= 200×10=2000N/S

mu= 200×5= 1000N/S

mv-mu=2000-1000=1000N/S

therefore p=1000N/s
