Momentum and Impulse questions What is the momentum of an 8kg bowling ball rolling at 2m/s? If the bowling ball rolls into a pillow and stops in 0.5s, calculate the average force it exerts on the pillow What average force does the pillow exert on the ball? What is the momentum of a 50kg carton that slides at 4m/s across an icy surface? The sliding carton skids onto a rough surface and stops in 3s. Calculate the force of friction it encounters What impulse occurs when an average force of 10N is exerted on a cart for 2.5s? What change in momentum does the cart undergo? If the mass of the cart is 2 kg and the cart is initially at rest, calculate its final speed A 2 kg blob of putty moving at 3m/s slams into a 2kg blob of putty at rest. Calculate the speed of the two stuck together blobs of putty immediately after colliding? Calculate the speed of the two blobs if the one at rest was 4 kg? In terms of impulse and momentum, why are air bags in automobiles a good idea? You can’t throw a raw egg against a wall without breaking it, but you can throw it at the
