Question

Which has more momentum, a `500kg` object moving at `1/4m/s` or a `50kg` object moving at `20m/s`?

Answer 1

`"50 kg"` object

Explanation:

Momentum (`"p"`) is given by

`"p = mass × velocity"`

`"p"_1 = 500\ "kg" × 1/4\ "m/s" = 125\ "kg m/s"`

`"p"_2 = 50\ "kg" × 20\ "m/s" = 1000\ "kg m/s"`

`"p"_2 > "p"_1`
