Question

What will be the velocity of an object of mass 6 kg if its momentum is 66.3 kg m/s?
m/

Answer 1

Answer:

11.05 m/s

Explanation:

Given, mass=6kg, momentum= 66.3 kg m/s

Momentum = mass * velocity

∴ $velocity = \frac{momentum}{mass}$

velocity= $\frac{66.3}{6\\}$

∴ v = 11.05m/s

Answer 2

Given:

• Mass = 6 kg
• Momentum = 66.3 kg m/s

To find:

• Velocity = ?

Solution:

Here apply the formula of momentum and find out the value of velocity.

Momentum = Mass × Velocity

In short

P = MV

Substitute the known values in the above mentioned formula.

➥ 66.3 = 6 × Velocity

⇒ Velocity = 66.3 ÷ 6

⇒ Velocity = 11.5 m/s

∴ Velocity of the object = 11.5 m/s

KNOW MORE:

• SI unit of Momentum is kg m/s.
• SI unit of mass is kg.
• SI unit of velocity is m/s.
