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?

a=(vu)/t
where v=final velocity, u=initial velocity and t= time in seconds
initial is 0 m/s
go from here yourself :) 
ok now Force
Force = mass*acceleration
use the acceleration you calculated in the first question to find the force exerted on the puck
