Question

A player uses a hockey stick to increase the speed of a 0.200 kg hockey puck by 6 m/s in 2 seconds. how 1. much did the hockey puck accelerat?

2. how much force was exerted on the puck?

Answer 1

a=(v-u)/t
where v=final velocity, u=initial velocity and t= time in seconds

initial is 0 m/s

go from here yourself :)

Answer 2

ok now Force

Force = mass*acceleration

use the acceleration you calculated in the first question to find the force exerted on the puck
