18. 2. The time a male bungee jumper is freely falling is 1.5 seconds .

19. a. What is the velocity of the jumper at the end of 1.5 seconds? b. How far does he fall?

20. 3. A juggler tosses three balls alternately vertically upward. Each ball has an initial velocity of 5 m/s. How high does each ball rise? How long does each ball remain in the air?

21. 4. Vincent drops a stone from a bridge 25 m above the water. With what velocity does it hit the water?

22. 5. A brick falls freely from a high scaffold and hits the ground after 3.5 seconds.

23. How high is the scaffold? What is the velocity of the brick just before hitting the ground?

24. 6. A body is dropped from rest and falls freely. Determine the position and the velocity of the body after 2.00 s have elapsed.
