Question

Which has more momentum, a `5kg` object moving at `4m/s` or a `20kg` object moving at `20m/s`?

Answer 1

The 20-kg object has the greatest momentum.

Explanation:

The equation for momentum is `p=mv`, where `p` is momentum, `m` is mass in kg, and `v` is velocity in m/s.

Momentum for 5 kg, 4 m/s object.

`p="5 kg"xx"4 m/s"=20"kg"*"m/s"`

Momentum for 20 Kg, 20 m/s object.

`p="20 kg"xx"20 m/s"="400 kg"*"m/s"`
