A 2.0-kg object moving 3.0 m/s strikes a 1.0-kg object initially at rest. Immediately after the collision, the 2.0-kg object has a velocity of 1.5 m/s directed 30 degrees from its initial direction of motion. What is the speed of the 1.0-kg object just after the collision?
a. 3.7 m/s b. 3.4 m/s c. 1.5 m/s d. 2.4 m/s e. 4.1 m/s
