TutorialsPart 1: Bowling Ball Collision
If there are no external forces causing an impulse on a system, we can assume that the total momentum of the system will be conserved. Use the overlay to measure and the included stopwatch on the slo mo video to measure a change in time in order to calculate velocity Use the conservation of momentum to calculate the mass of the bowling ball on the left if the one on the right has a mass of 5.6 kg Part 2: Potato Gun Ballistic PendulumA clever way to measure the velocity of a very fast projectile (like a potato out of a potato gun) is to fire it into a more massive pendulum and measure the highest point in the swing. Step 1 - Conservation of EnergyUse the conservation of energy and the maximum height of the bucket’s swing to calculate the top velocity of the bucket and potato when it starts swinging after the collision. Step 2 - Conservation of MomentumUse the conservation of momentum and the velocity of the potato/bucket system from part 1 to calculate the initial velocity of the potato
