A man of mass 50 kg starts moving on the earth and acquires speed of 1.8 m/s. With what speed does the earth recoil? Mass of earth =`6xx10^24kg.`

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
`p_i=p_f`
`:. 0=50(1.8)+(6xx10^24)v`
`:. v=-1.5xx10^-23m//s`
Negative sign implies the opposite direction of the velocity of man.
