Question
A 3 kg object traveling 6m/s east has a perfectly elastic collilsion with a 4kg object traveling 8 m/s west After the sollision, the 3 kg object will travel 10 m/s west
a. What was the total momentum before the collision?
b. What is the total momentum of these objects after this collision?
c. What velocity will the 4 kg object have after the sollision?
a. What was the total momentum before the collision?

a. momentum is a vector: 4*8W-3*6W=?
b. momementum after = momentum before.
c. solve that by doing the conservation of momentum
b. momementum after = momentum before.
c. solve that by doing the conservation of momentum
