Part A = 0

Part B = equal to

Part C = 500 kg·m/s

What is the momentum PA,i of piece A before the explosion?

During the explosion, is the force of piece A on piece B greater than, less than, or equal to the force of piece B on piece A?

The momentum of piece B is measured to be 500 kg·m/s after the explosion. Find the momentum PA,f of piece A after the explosion.

Part A = 6.72 cm/s

Part B = 11.0 cm/s

If Olaf catches the ball, with what speed v_{f} do Olaf and the ball move afterward?

If the ball hits Olaf and bounces off his chest horizontally at 7.40 m/s in the opposite direction, what is his speed after the collision?

Part A = θ_{f} = θ_{i}

Part B = F = 2mv_{i}sin(θ_{f})/(Δt)

What is the final angle θ_{f} that the ball’s velocity vector makes with the negative y axis?

What is the magnitude F of the average force exerted on the ball?

Part A = perfectly inelastic

Part B = momentum only

Part C = v_{f} = m_{b} ˙ v_{i} / (m_{b} + m_{w})
