Question

Which has more momentum, a `7kg` object moving at `3m/s` or a `4kg` object moving at `7m/s`?

Answer 1

Momentum is the product of mass and velocity.

For the `1` st object momentum is `7×3=21 Kg.ms^-1`

And for the `2` nd object momentum is `4×7=28 Kg.ms^-1`

So,clearly the `2` nd object has higher momentum.
