Impulse Momentum Equations

A force of 4 N is applied to a ball for 0.75 s. What is the impulse?

• FΔt = mΔv

• J = p

• p = mv

A 40 g superball strikes a wall with a velocity of 10 m/s that is normal to the wall. It bounces away at a velocity of 7 m/s, still normal to the wall. If the bounce lasted 0.1 s, what is the force between the ball and the wall?

• FΔt = mΔv

• J = p

• Δp = mΔv

• J = FΔt

A 0.105 kg hockey puck is traveling at 12 m/s when it is struck by a stick. As a result, the puck travels at 15 m/s in the opposite direction. If the contact between the stick and puck lasted 0.05 s, what was the force?

• FΔt = mΔv

• J = p

• Δp = mΔv
