A 0.5-kg cart on an air track moves 1.0 m/s to the right, heading toward a 0.8-kg cart moving to the left at 1.2 m/s. What is the direction of the two-cart systems momentum?

A 23.6 kg dog is running northward at 2.83 m/s, while a 7.27 kg cat is running eastward at 2.83 m/s. Their 70.2 kg owner has the same momentum as the two pets taken together.

person weighing 980N is walking in the direction of West at 5m/s. Suppose the heavy wind stared blowing the person in such a way that the person started walking back in the direction of East at 9m/s, what is the change in the momentum of the person?

A 2017 Mercedes B-Class is travelling 27 m/s and is brought to a complete rest by large a tree (which weighs 1000 kg). The car weighs 1345 kg and has no other passengers. The driver is a 5’9 adult male who weighs 79 kg. The momentum prior to the crash is 36135 kgm/s. What is the momentum after the crash?

A 10 kg cart is traveling at a velocity of 4 m/s in the rightward direction. It strikes a 7 kg cart also traveling at 6 m/s also in the rightward direction. The carts stick together after impact. What is the final velocity of the two-cart system?

A firecracker is moving to the left before it explodes. Right after exploding, it breaks off into two pieces of equal mass, one travelling to the left and the other travelling to the right. Which one has the higher speed – the piece travelling to the left or the piece travelling to the right? Answer using ideas of momentum.

A 480 kg car moving initially at 20.0 m/s east hits head-on a 520 kg car moving initially at 10.0 m/s west. After the collision, the cars are stuck together. If linear momentum is conserved, what is the velocity of the cars together after the collision?

A 20 kg object and a 30 kg object collide. The figure below is for the 20 kg object. Assume momentum is conserved and find the change in velocity of the 30 kg object over the entire time shown. am/sis) 30.0 25.0 20.0 15.0 10.0 5.0 2.0 4.0 6.0 t(s)

A big fish of mass 15 kg moving to the right at 4 m/s swallows a little fish mass of 3 kg moving towards it at 6 m/s. What is the velocity of the big fish after it swallows the small fish?

A cart of mass 0.3kg traveling at 3m/s on a horizontal frictionless track collides with a cart of mass 0.45kg traveling at 2.5m/s towards it.  The carts stick together after the collision.  What is the final velocity of the carts
