Question

A 5kg ball is traveling at the same speed as a 10 kg ball. compared with the 5 kg ball, the 10 kg ball has

1) half the momentum

2) twice the momentum

3) five times the momentum

4) the same momentum

Answer 1

2) twice the momentum

Explanation:

p=mv

momentum had a directly proportional relationship to mass, what this means is that if you somehow increase the mass of the object twice the momentum will also increase twice, if the mass decreases by 5 times the momentum will also decrease by 5 times. Therefore, since the 10 kg object is twice the mass of the 5 kg object, so is its momentum relative to the 5 kg object. (5×2=10) 2p=2m
