How do I cancel out the kg in this: 2kg*m/s = (1kg)(V2)?

Question

When you divide the same units into something (like 10kg/5kg) the unit remains. I know the answer is 2 m/s, but how do I get there?

Answer 1

When you divide two values with the same units, the unit is cancelled; it doesn't remain as you thought. So (10 kg) / (5 kg) = 2, with no units.

2kg*m/s = (1 kg)(v_2) ==> v_2 = 2 m/s

Answer 2

divide both sides by 1kg

then you get 2m/s=V2
