3-139.

Recall that speed is the absolute value of velocity.

|*v*(4)| = |− 32| = 32

Don't forget the units!

final position = initial position + displacement

intial position is 100 meters

Displacement is area between the velocity curve and *x*-axis. Notice that the area is negative (below the *x*-axis).

Total distance of the drop = area under a SPEED graph.
