Question

Which of the following best describes the acceleration of a bungee jumper during free fall? -constant -negative -zero -positive

Answer 1

Constant

Step-by-step explanation:

An object (or a person) is said to be in free fall if the only force acting on it is the force of gravity.

The force of gravity acting on an object is:

F = mg

where m is the mass of the object, g is the acceleration of gravity.

According to Newton's second law, the acceleration experienced by the object is:

`a=(F)/(m)=(mg)/(m)=g`

As we can see, the acceleration of the object does not depend on the time, but it is constant and its value is
`g=9.8 m/s^2` (downward). Therefore, the acceleration of a bungee jumper is constant.
