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* velocity}}}`

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

`\longrightarrow\sf{Momentum=72 * 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
