To calculate the impulse of a object, you have to find the product of the force and the change in time which is known as final time subtracted by the initial time.

1. How much impulse is applied by a 25 N force in 30 seconds?

2. How much impulse is required to change the velocity of a 2500 kg truck by 15 m/s?

3. What will be the change in velocity of a 850 kg car if a force of 50,000 N is applied to it for 0.5 seconds?

4. A 50,000 kg train is rolling on its own down the track at 5 m/s. You grab the rope trailing behind it, and exert a stopping force of 2000 N. How long does it take to stop the train?

5. A 1,100 kg car is going at 22 m/s. What force is needed to stop it in 2.0 seconds?
