Question

What is the magnitude of the momentum of a 28-g sparrow flying with a speed of 8.4 m/s?

Answer 1

momentum = mass×velocity
=28×8.4
=235.2 kgm/s
or
=0.2352 GM/s

Answer 2

The momentum of the sparrow is 0.23 kg-m/s.

Explanation:

Given that,

Mass of sparrow, m = 28 g = 0.028 kg

Speed of the sparrow, v = 8.4 m/s

To find,

The momentum of sparrow.

Solution,

The momentum of an object is equal to the product of mass and velocity. It is given by :

p = mv

$p=0.028\ kg\times 8.4\ m/s$

p = 0.23 kg-m/s

So, the momentum of the sparrow is 0.23 kg-m/s.
