INELASTIC COLLISION - Guided Practice - We will work on this problem together and you will show all work.
A 2.0 kg ball traveling east at +4.o m/s collides head on with a 1.0 kg ball traveling west at -8.0 m/s. After the collision, the two balls stick together. What is the final velocity of the two balls stuck together after the collision?

ELASTIC COLLISION - Guided Practice - We will work on this problem together and you will show all work.
A toy truck, with a mass of 15.0 kg travels along a level table top at +1.0 m/s. A miniature car. with a mass of 5.0 kg, speeds headlong toward the toy truck at -0.75 m/s. Immediately after the collision, the 15.0 kg toy truck continues in its original direction at +0.13 m/s. What is the velocity of the 5.0 kg miniature car after the collision?
