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

Respuesta :

Answer:

Constant

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:

[tex]a=\frac{F}{m}=\frac{mg}{m}=g[/tex]

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