Question:
KE of Red Cart = KE of Blue Cart = Sum of KE of Red and Blue carts = **Compare the total KE before and after the explosion. Is KE conserved during explosive events? Where did the KE come from? I-B (equal masses in motion) We will fire the carts again (leaving each mass at 1 kg), but this time we will give them an initial velocity before the explosion. Do this by setting the initial velocity to +2 m's for either cart, as they are coupled together. Fire the carts and notice their motion. Initial momenta before the explosion = (this is not zero) Initial KE before the explosion =
