Question

A 5kg traveling at 4 m/s slams into a 1kg object and sticks to it. What will the final velocity of the two objects be?

Answer 1

Below

Step-by-step explanation:

Using conservation of momentum

mv = mv

5(4) + 1(0) = (4+1) v

( this assumes the 1 kg mass was not moving before being struck)

20 = 5 v

v = 4 m/s
