Question

A body of mass 'M' moving with velocity 'V' explodes into two equal parts. If one part comes to rest and the other part moves with velocity 'v₀'. What would be the value of 'v₀'?

Options

• V

• 2V

• `V/sqrt2`

• 4V

Answer 1

2V

Explanation:

By law of conservation of momentum

`"MV"="M"/2"v"_0`

∴ v₀ = 2V
