2 In ice hockey, players use a stick to hit an object called a puck, across the surface of the ice.
Assume that the frictional force between the ice and the puck is negligible.
The mass of each puck is 0.16 kg.

(b) A player hits a single, stationary, puck. The stick is in contact with the puck for a time of 0.033 s
and the puck moves at a velocity of 20 m s–1 across the ice.
Calculate:
(i) the impulse of the force applied to the puck. Include an appropriate unit.
impulse = ................................... unit ............... [2]
(ii) the average force F that the stick exerts on the puck.
