Question 1
part 1 of 2
10 points
The tallest volcano in the solar system is the
24 km tall Martian volcano, Olympus Mons.
Assume:
An astronaut drops a ball off the
rim of the crater and that the free fall acceler
ation of the ball remains constant throughout
the ball’s 24 km fall at a value of 3
.
2 m
/
s
2
.
(We assume that the crater is as deep as the
volcano is tall, which is not usually the case
in nature.)
a) Find the time for the ball to reach the
crater floor.
Answer in units of s.
Question 2

10 points
b) Find the magnitude of the velocity with
which the ball hits the crater floor.
Answer in units of m
/
s.

A
stone
is
thrown
straight
up
ward
and
at
the
top
of
its
trajec
tory
its
velocity
is
momentarily
zero.
What is its acceleration at this point?
1.
Zero
2.

down
4.
Unable to determine
Question 4
part 1 of 1
10 points
The acceleration due to gravity on planet
X is one fifth that on the surface of the earth.
If it takes 4
.
2 s for an object to fall a certain
distance from rest on earth, how long would
it take to fall the same distance on planet X?
