1.) How much impulse does a 10 N force produce if it is applied in 0.05s?
2.) A 0.80kg object at rest is given a force of 4.0N during a time interval of 2.0s What is the velocity of the object at the end of this time interval ?
3.) A 5.0kg ball rolls into a pillow at 2.0 m/s and stops in 5.0s, what is the average force exerted on the pillow?
4.) A 1500kg car moving east speeds up uniformly from 5.0 m/s to 30m/s in 8.0s. What constant force acts on the car
5.) How long must a 1500N force act on a 50kg cart to increase its speed from 50 m/s to 150 m/s
6.) A 300g ball moving at 20 m/s is hit by a bat. After the impact, the ball rebounds at the same speed along the same line. What was the impulse exerted by the bat on the ball?
