If you do the same old things, you get the same old results! Monday, 12/15/08 PHYSICS If you do the same old things, you get the same old results! RECALL: ptotal initial = ptotal final if no NET external force is acting (*demo carts*) energy demos 1/2 balls and astroblaster ex. After being struck by a bowling ball, a 1.5kg bowling pin sliding to the right at 3.0m/s collides head-on with another 1.5kg bowling pin initially at rest. Find the final velocity of the second pin if the first pin moves to the right after the collision at 0.5m/s. 2.5m/s to the right
