Question

Which has more momentum, an object with a mass of `5kg` moving at `8m/s` or an object with a mass of `2kg` moving at `7m/s`?

Answer 1

The first object has more momentum.

Explanation:

Momentum is the product of mass and velocity:

`=> p = mv`

For the first object:

`=>p_1 = 5xx8 = 40 " kg"* "m/s"`

For the second object:

`=>p_2 = 2xx7 = 14 " kg"* "m/s"`

Hence, the first object has more momentum.
