Sergei tees off on a stationary hockey puck using his most powerful slap shot. If he can exert a force of 250 N on the 500 gram puck for a time of 0.1 seconds, what velocity will he give to it, and how far will the puck move in the time it is on his stick?

Answer: velocity = 50m/s

Distance moved=5m

Explanation:

Using the formula Ft=Mv i. e impulse = momentum

Where F = force, t = time, M = mass, v = velocity

In this case we need to find v,

F, t, M are all given in the question.

Therefore, substituting the values we have

250N*0.1s=0.5kg*v. Mass=500g = 0.5kg

v=25/0.5 = 50m/s

The distance the puck will move when it is on his stick.

D = Velocity * time

D=50m/s * 0.1s

D=5m

Goodluck ...
