19 km tall Martian volcano, Olympus Mons.

An astronaut drops a ball off the rim of the

crater and that the free fall acceleration of the

ball remains constant throughout the ball’s

19 km fall at a value of 4 m/s2. (We assume

that the crater is as deep as the volcano is tall,

which is not usually the case in nature.)

Find the time for the ball to reach the crater

floor.

Answer in units of s.

**Find the magnitude of the velocity with which**

the ball hits the crater floor.

Answer in units of m/s.

the ball hits the crater floor.

Answer in units of m/s.

## Homework Equations

Vf = Vo +at

## The Attempt at a Solution

I simply plugged in values from the first problem's answer, 97.468s, along with the given acceleration and implied initial velocity to make:

Vf = (-4m/s)(97.468s) = -389.872 m/s

This was wrong though, so I'm wondering where I screwed up along the way.
