Question 6 6. Which of the following is true for an object in stable equilibrium?

Question 7 7. Which of the following is true for an object in neutral equilibrium?

Question 8 8. Using the center of gravity of an object, how do we tell when the object has reached its tipping point?

Question 9 9. An object will experience an acceleration if:

Question 10 10. Acceleration is:

Question 11 11. Which of the following units would be correct for an acceleration?

Question 12 12. Average acceleration is calculated by:

Question 13 13. Momentum is the quantity of ______ of a moving body.

Question 14 14. The three types of collisions are elastic, perfectly inelastic, and partially inelastic. Assuming the collision is in an isolated system, in which of these three types is momentum conserved?

Question 15 15. You have a bowling ball weighing 5.4 kg, which you throw at a velocity of 10 m/s. It hits a 3.6 kg ball sitting still in the lane (0 m/s). The bowling balls are made of wet clay, so when they hit, they stick together. Find the velocity of the two balls stuck together after the collision. (hint: The equation for conservation of momentum of an elastic collision is: m{1} * v{1i} + m{2} * v{2i} = m{1} * v{1f} + m{2} * v{2f}).
