**Meteorite Impulse Simulation**

Obj: Determine the Physics of Meteorite Impacts

**Materials:** meter stick, meteorite, sand box, vernier
caliper, ruler** **

**Methods
and Analysis**

1. Sketch the initial setup, and
show the measurements to be taken and calculations to perform.

2. Determine a release height for
the golf ball (usually >2 m) above the sand box.

3. Calculate (before the
drop) the weight of the golf ball, the time to fall, its velocity, impulse, and
momentum immediately prior to impact with the sand. Show all equations, work, units.

4. After impact, measure the
depth of the crater.

5. Based on the depth of the
crater, calculate the acceleration of the ball while slowing down in the sand, average
force applied by the sand, time to stop, and the impulse the sand applied to
the ball.

6. **Compare** in a table the
following of your measurements and calculations *before and after impact*:

a) force applied to golf ball

b) time of impulse

c) acceleration

d) impulse

e) change in momentum

7. Assuming a refrigerator-sized
meteorite (100 kg) strikes a sand desert on the earth at a terminal velocity of
300 m/s, predict the crater’s depth based on data gathered in this lab.
