Physics of Impulse

Today, you will be figuring the impulse of three different systems using videos.  In each, you will need to determine the mass of a ball in kg, so you will need to use the logger pro and a force probe as a scale.  Attach a cup to the force scale, weigh it, drop in the ball, weigh it, and then subtract the difference.  Convert that value to kg using  F=ma      Show work on one of the trials.


Trial 1:  What impulse is transferred from a pool cue to the cue ball during a hit?


Trial 2:  What impulse is transferred from the cue ball to the ball that is hit?


Trial 3:  What impulse is transferred from a ball to the bumper as it is hit.


Analzye the three videos on logger pro to determine the change in velocity.   The time it takes for the collision  will show on the dot-analysis.   For each printed trail, show me the calculation for the change in velocity (v(final) - v(initial), the change in momentum (m* change in velocity), the impulse value, and the Force applied.
