1) A wrench is thrown at your head at a velocity of 14m/s. It takes 0.3s to make contact. How far
did the wrench travel?
2) From rest you run 20m in 2.6s. What is your velocity?
3) Determine the amount of time it takes a large javelin to hit you if it travels with a final velocity
of 17.3m/s starting from rest. The acceleration rate is 2.7m/s2
4) What is the rate of acceleration of a bowling ball traveling at an initial velocity of 6.3m/s to
1.6m/s over a period of 4.2s?
5) You are thrown off of a cliff. You start at rest and fall for 5.3s. What is your final velocity?
6) A  B  C  D E. Find the total distance and displacement.

7) Calculate the final velocity of a rock that has a mass of 2.4kg. The rock starts from rest and travels
east with an acceleration of 4.6m/s2 over a period of 12s.
