2. ..... is how far an object has traveled
3. If Michael Jordan has a vertical leap of 1.29 m, then what is his takeoff speed if his acceleration is-9.8 m/s$^{2}$ and his velocity at the top of his leap is 0 m/s?
4. A Ferris wheel starts at rest and builds up to a final angular speed of 0.70 rad/s while rotating through an angular displacement of 4.9 rad. What is its average angular acceleration?
5. Juan is standing on the top observation deck of the Eiffel Tower in Paris at a height of 300 meters. He drops his cell phone. How fast will the phone be traveling when it hits the ground? Ignore the effect of air resistance.
6. What is the velocity of an object that has been falling freely in a vacuum for 2 seconds?
