Question
A student jumped on a trampoline. In the picture
above, she has stretched the trampoline as much as it
will stretch on this jump. Her body (her center of
mass) has moved as low as it will go. A graph of the
height of her body as a function of time would show
only curved lines (no sharp corners and no straight line
segments). Which of the following correctly describes
the acceleration of the student when the center of
mass of the student is at its lowest point (at the
instant shown in the picture above)?
O Her acceleration points up.
O Her acceleration is between zero and 9.8 meters per
second squared, pointing down.
O Her acceleration is zero.
O Her acceleration is greater than 9.8 meters per second
squared, pointing down.
O Her acceleration is 9.8 meters per second squared,
pointing down.
