Question

The linear momentum of an object of mass 2 kg is 10 kg m/s. The velocity of the object is​

Answer 1

Answer:

Mass=2kg

velocity=10m/s

So the net force on the body is:

f=ma

2×10=20N

hope this answer is helpful for you.

Answer 2

Given:

An object with

• Mass = 2 kg
• Linear Momentum = 10 kg m/s

What To Find:

The velocity of the object.

Formula:

Linear momentum (p) = Mass (m) × Velocity (v)

Solution:

Using the formula,

⇒ Linear momentum (p) = Mass (m) × Velocity (v)

Substitute the values,

⇒ 10 kg m/s = 2 kg × v

Take 2 kg to LHS,

⇒ $\sf{\dfrac{10 \: kg \: m/s}{2 \: kg} = v}$

Cancel 10 kg and 2 kg,

⇒ $\sf{5 \: m/s = v}$

∴ Thus, the velocity of the object is 5 m/s.
