During a bungee jump, a studen
During a bungee jump, a student (i) initially moves downward with increasing speed and then (ii) moves downward with decreasing speed, (iii) reaches the turnaround point (that is, the low point of the motion), (iv) moves upward with increasing speed, and finally (v) moves upward with decreasing speed. For each situation (i) through (v), state the direction of the bungee jumper’s velocity and acceleration (that is, upward, downward, or zero). Note: (i), (ii), (iv), and (v) refer to intervals of motion, whereas (iii) refers to an instant.
