What is the final velocity of the lighter object? (See below)
Two objects whose masses are #1 kg# and #4 kg# collide with equal and opposite velocities of magnitude #10 m^-1# . They bounce off one another, and the heavier object has a final velocity of #5ms^-1# in its original direction. What is the final velocity of the lighter object?

The problem is incorrectly specified. The heavier object continues on at
Explanation:
Given:
NOTE: I have chosen the direction of the velocity of the lighter object to be positive and the direction of the velocity of the heavier object to be negative.
Take the following equation from this Momentum reference to check whether the initial information is consistent:
We know all of these values:
Let's find the velocity of
10 m/s in the direction opposite its original motion.
Explanation:
Solving for
Since
