# PROJECTILE MOTION LAB

## PURPOSE:

To study projectile motion under a "real" situation.

## PROCEDURE:

- Calibrate your ramp. Determine the velocity of the ball as
it leaves the ramp when rolled from different starting points
along the ramp. Use the projectile motion of the ball onto the
table top for your calculations. You should calibrate many points,
at least every 2 cm or even every cm. Note the letter of your
ramp.

- After the ramp has been calibrated, it will be placed on a
platform at an given height,
**H**, and a cup will be placed
on the floor at a given distance from the ramp, **R**. Your
goal is to release the ball from the point your decide along the
ramp so that it will gain enough speed to just hit the cup.

## SCORING:

Hit on 1st try = 10 points
Hit on 2nd try = 7 points

Hit on 3rd try = 3 points
