Question

Which has more momentum, a 0.046-kg golf ball with a speed of 60.0 meters per second, or a 7.0-kg bowling ball with a speed of 6.0 meters per second?

Answer 1

The 7.0-kg bowling ball with a speed of 6.0 meters per second

Step-by-step explanation:

Momentum is p=mv

m = mass, v = velocity. (velocity is speed with direction)

1. 0.046-kg golf ball with a speed of 60.0 meters per second.

The mass is 0.046kg , velocty is 60.0
`ms^(-1)`

p= mv = 0.046 x 60 = 2.76kg
`ms^(-1)`

2. 7.0-kg bowling ball with a speed of 6.0 meters per second

Mass is 7kg, velocity = 6

p=mv = 7 x 6 = 42kg
`ms^(-1)`

The 7.0kg bowling ball has more momentum because 42 is greater than 2.76.
