Question

Q1.The linear momentum of an object of mass 2 kg is 10 kg m/s. The velocity of the object is​:

Answer 1

Explanation:

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,

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

Cancel 10 kg and 2 kg,

$⇒ \sf{5 \: m/s = v}5m/s=v$

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