# Problem: 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

###### FREE Expert Solution

Impulse is expressed as:

$\overline{)\begin{array}{rcl}\mathbf{I}\mathbf{m}\mathbf{p}\mathbf{u}\mathbf{l}\mathbf{s}\mathbf{e}& {\mathbf{=}}& {\mathbf{F}}_{\mathbf{a}\mathbf{v}}\mathbf{∆}\mathbf{t}\\ & {\mathbf{=}}& \mathbf{m}\mathbf{∆}\mathbf{v}\end{array}}$, 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.
