APFIVE Conservation of Linear Momentum
A 2.0 kg object traveling at 3.0 m/s collides with a 1.0 kg object that is initially at rest. Following the collision, the 2.0 kg object moves in its original direction with a speed of 1.0 m/s. Assuming the total momentum of the system is conserved, what is the velocity of the 1.0 kg object after the collision?
A
4.0 m/s in the original direction
B
6.0 m/s in the original direction
C
3.0 m/s in the opposite direction
D
2.0 m/s in the original direction
