1. The magnitude of an object's momentum is 23[kg*m/s]. If the velocity of that object is doubled, the new momentum of the object is?

The momentum and velocity of an object is directly proportional. Therefore if the velocity is doubled, the momentum is also doubled.

2 * 23[kg*m/s] = 46[kg*m/s]

2. A mother pushed a child on a swing by exerting 15N force over a time of .3s. What impulse is delivered to the child?

J = FΔt

J = 15[N] * .3[s]

J = 4.5[N s]

3. An impulse of J is applied to an object. The change in the momentum of the object is?

1. J

4. Momentum may be expressed in

4. Newton-seconds
