Question

(i) A body of mass 10 kg is moving with velocity 2 m/s. Calculate its linear
momentum.​

Answer 1

Given :

• Mass of a body, m = 10 kg

• Velocity of a body, v = 2 m/s

To find :

• Linear momentum, p

According to the question,

As we know,

Linear momentum is the product of mass and velocity.

So,

➞ Linear momentum = Mass × Velocity

➞ Linear momentum = 10 kg × 2 m/s

➞ Linear momentum = 20 kg m/s

So,the linear momentum is 20 kg m/s.

MORE DETAILS :-

• Linear momentum is denoted as p.
• SI unit of linear momentum is kg m/s.
• CGS unit of linear momentum is g cm/s.
• Mass is denoted as m.
• Velocity is denotes as v.
• SI unit of mass is kg.
• SI unit of velocity is m/s.

Answer 2

Answer:

Given :-

• A body of mass 10 kg is moving with velocity of 2 m/s.

To Find :-

• What is the linear momentum.

Formula Used :-

$\boxed{\bold{\large{p\: =\: mv}}}$

where,

• p = Momentum
• m = Mass
• v = Velocity

Solution :-

Given :

• Mass = 10 kg
• Velocity = 2 m/s

According to the question by using the formula we get,

⇒ p = 10 kg × 2 m/s

➠ p = 20 kg m/s

$\therefore$ The linear momentum is 20 kg m/s .
