II-C (unequal masses, M1 > M2 both in motion) Now set the Red Cart to 3 kg with a velocity of +7 m/s, while the Blue cart is set to 1 kg and is moving at -5 m/s. Record your observations of the motion below. Initial Momenta Red Cart = Initial Momenta Blue Cart = (include direction by using the appropriate sign) Total Initial Momentum = (include direction by using the appropriate sign) Initial KE of Red Cart = ; Initial KE of Blue Cart = Sum of KE of Red and Blue carts = After the Collision
