The tallest volcano in the solar system is the
17 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
17 km fall at a value of 3.3 m/s
2
. (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
002 (part 2 of 2) 10.0 points
Find the magnitude of the velocity with which
the ball hits the crater ﬂoor.
Answer in units of m/s

H = .5 g t^2

1.7x10^4 = .5 * 3.3 * t^2

1.03x10^4 = t^2

2) multiply the fall time (t) by the acceleration (3.3 m/s^2) to find the final velocity
