Lab: Trajectories
Date perform: September 14, 2016
Lab group: Michael Flores, Alex, and Michael
Purpose: Use projectile motion to predict the impact point of a ball on an incline board.
Theory: Derive an equation for trail without the board to find the velocity to help find the distance for the trail with board.
Apparatus: In this lab we made a ramp with metal poles for a marble on the table. Then we roll down the marble to see where it impact the floor. We had a carbon paper to get a accurate measurement where marble hit the floor. We then use a plumb ball to measure the height. After that we did the same thing, but added a wood board and made sure the marble impact on the board. Here a picture of the lab we did.

The measure we obtain without the board were a height a 94.2 cm where the ball was launch at and a distance of 78 cm from the table. To determine the launch speed, we did this:

Then we added the board and tried to find the distance of the impact. we were able to get the distance with theses calculations:

The distance of the marble from the board and with out the board were very similar. Both of their height were the same and the X distance were off by less than six centimeters. For both trials their would be uncertainty by 0.001 meter form the height and distance from the table.
