2. how much force was exerted on the puck?

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 :)

ok now Force
Force = mass*acceleration
use the acceleration you calculated in the first question to find the force exerted on the puck
Force = mass*acceleration
use the acceleration you calculated in the first question to find the force exerted on the puck
