Question

a body of mass 25kg has a momentum of 100 kgm/s what is it's velocity

Answer 1

Pretty simple.
Momentum=Mass×Velocity.
100=25×v.
v=100/25
v=4m/s

Answer 2

Given:

• Mass (m) = 25 kg
• Momentum (p) = 100 kgm/s

To Find:

• What is the Velocity?

Formula Used:

$\\ \bigstar{\underline{\boxed{\sf\green{ Momentum = Mass \times Velocity }}}}$

Solution:

After Substituting the Values;

$\colon\implies{\sf{ 100 = 25 \times v }} \\ \\ \colon\implies{\sf{ \cancel{ \dfrac{100}{25} } = v }} \\ \\ \colon\implies{\sf\red{ v = 4 \: m/s }}$

Hence,

The Velocity of a body is 4 m/s.

Remarks:

• P = Momentum
• M = Mass
• V = Velocity
