Question

If the mass of an object is 10 kg and the velocity is 8 m/s, what is the momentum?
A. 8 kgm/s
B. 120 kgm/s
C. 80 kgm/s
D. 40 kgm/s

Answer 1

Answer:

80 kgm/s

Explanation:

Momentum = Mass x Velocity

It can be expressed as $\displaystyle{p = mv}$ where p is momentum, m is mass and v is velocity.

We know that mass is 10 kg and velocity is 8 m/s - therefore, substitute the given information in formula:

$\displaystyle{p=10 \ \times \ 8}\\\\\displaystyle{p=80 \ \ kgm/s}$

Hence, the momentum is 80 kgm/s.
