2. A grocery cart has a mass of 3 kg, and the groceries have a mass of 8 kg. When the groceries are in the cart, it is moving at a velocity of 4.5 m/s. Calculate the total momentum of the cart and the groceries.

3. What is the change in momentum caused by exerting a force of 62 N on an object for 0.0685 seconds?

4. What is the impulse on a 20 kg object when it changes its velocity from 30 m/s to 18 m/s?

5. An egg has a mass of 12 kg and is thrown towards Izaiah, who has a mass of 32 kg, at a velocity of 7 m/s. Izaiah is motionless. If the egg hits and sticks to Izaiah, what will their new velocity be?

6. What is the impulse on a 40,000 kg truck when it accelerates from a velocity of 2 m/s to 15 m/s?

7. A librarian with a mass of 98 kg picks up a stack of books. The books have an additional mass of 20 kg. If the librarian is moving at a rate of 5 m/s, what is the total momentum of the librarian and the books?

8. What is the momentum of a 65 kg object moving at 5.5 m/s?

9. A slime ball has a mass of 9 kg and is thrown with a velocity of 10 m/s at Kenia, who has a mass of 50 kg. Kenia is initially at rest, but when the slime ball hits her it sticks. What will their new velocity be?

10. What is the change in momentum caused by exerting a force of 42 N on an object for 0.0785 seconds?

11. A piece of chewed bubble gum has a mass of 2.5 kg. The gum is thrown at Ali with a velocity of 9 m/s. Ali (m = 40 kg) is initially at rest, but the gum sticks to her. What will their new velocity be after the collision?
