Question

What is the momentum of a man of mass 75kg when he walks with a velocity of 2m/s? 

115 kg m/s

150 kg m/s

125 kg m/s

110 kg m/s​

Answer 1

ANSWER

150 kg/ ms-¹

STEP BT STEP EXPLAINATION

m = 75 kg

v = 2 m/s

Linear momentum (p) = m× v

=75×2

150m/s

Answer 2

Answer :

• (b) 150 kg m/s

Given :

• Mass of Man = 75 kg
• Velocity of Man = 2 m/s

To find :

• the momentum of the man

Solution :

⇒ Let's find the momentum of the man.

→ Momentum = mv

Here,

• m = mass
• v = velocity

----------

→ Momentum = momentum × velocity

= 75 × 2

= 150

= 150 kg m/s

• Therefore, the momentum of man is 150 kg m/s.
