1 Object. The car. (Boulder doesn’t count because it never intercepts the car.)

16. Beside #15, write what combines/connects this problem.Vf at end of 1D = Vi at beginning of 2D

17. Above the car, finish this sentence, “Velocity is ____” (the definition) speed in a direction or displacement divided by time.

18. Find the final velocity before the car goes over the cliff.

V = 27.4 m/s
