Practical Physics Impulse and Momentum

A bicycle has a momentum of 24 kg•m/s. What momentum would the bicycle have if it had the same mass and was moving with one-half the speed?

• twice the momentum; 48 kg*m/s

• 1/2 the momentum; 12 kg*m/s

• 4x the momentum; 96 kg*m/s

• 1/4 the momentum; 6 kg*m/s

How does applying a larger force over a shorter time period affect the impulse delivered to an object?
