Question

Calculate the momentum of a 75 kg mass person walking at 2 m/s

Answer 1

⠀

$\huge{\underline{\underline{\sf{\blue{SOLUTION:-}}}}}$

$\sf{\underline{\pink{Answer-}}}$

• The momentum of a man is 150 kg.m/s.

⠀$\sf{\underline{\pink{Given-}}}$

• The momentum of a man of mass 75 kg when he walks with a uniform velocity of 2m/s.

⠀$\sf{\underline{\pink{Find-}}}$

• We have to find momentum of that man.

⠀$\sf{\underline{\pink{Explanation-}}}$

$\longrightarrow\sf{Mass, \: m= \: 75kg}$

$\longrightarrow\sf{Velocity, \: v= \: 2m/s}$

$\sf{\underline\green{Formula\:Used\:Here-}}$

$\bigstar \: \boxed{\sf{\red{ Momentum=mass\times velocity}}}$

$\sf{\underline{\pink{Putting\:the\:values:-}}}$

$\longrightarrow\sf{Momentum=72 \times 2kg.m/s}$

$\longrightarrow\sf150kg.m/s$

• Thus, momentum of a man is 150 kg.m/s.

⠀

$\sf{\underline{\green{Additional\: Information-}}}$

• Momentum is vector velocity.

⠀

• Momentum = force acting on the particle.

⠀

• Momentum is measurement of mass.

Answer 2

Momentum= M*v = 75*2= 75*2= 150kgm/s
