Homework Statement
Object a Mass 6kg moving velocity 5m/s is followed by a second object mass 8kg velocity 8m/s in the same straight line.
If the two objects are joined together after collision and move in the original direction, calculate heir common velocity.
The Attempt at a Solution
Now have either:
6x5 - 8x8 = 14V
-34 = 14V
-34/14 = V
V = -2.42m/s
or 5x6 + 8x8 = 14V
94 = 14V
94/14 = V
V = 6.71m/s
Which one is right?
Thanks in advance
