Question

A .1kg hockey puck is sliding along the ice with an initial velocity of 6 m/s when a player strikes it with his stick, causing it to speed up and travel with a velocity of 22m/s after. If the stick with in contrast with the hockey puck for .5 seconds, what was the average force applied tot he hockey puck?

Answer 1

F = Δp/Δt

= mΔv/Δt

= 0.1*(22 - 6)/.5

= 3.2 N
