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- Initial KE before the explosion- AC 2m/s After the explosion: velocity Red Cart= -8 m/s (include direction by using the appropriate sign) velocity Blue Cart - 12m/s (this is not zero) Momentum of Red Cart 1/-8m/s -0.125; Momentum of Blue Cart=1/12 m/s 0.084 (include direction by using the appropriate sign) Sum the momentum of Red and Blue carts = ****Compare the initial momentum before the collision to the total momentum after the collision. Is momentum conserved? 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?
