Impulse is expressed as:
, m is the mass of the hockey puck and Δv is the change in velocity.
The initial velocity is:
v0 = v1i
Let's take velocity to the right to be positive and to the left to be negative.
A hockey puck is traveling to the left with a velocity of v1 =10 m/s when it is struck by a hockey stick and given a velocity of v2 =20 m/s as shown. Determine the magnitude of the net impulse exerted by the hockey stick on the puck. The puck has a mass of 0.2 kg
