In the above example, assuming that the bench on which Mahendra is sitting is frictionless, starting with zero velocity, what will be Mahendra's velocity of motion towards Virat after 1 s? Will this velocity change with time and how?

Verified by Experts

Given : Force of Mahendra =
`F=4.002xx10^(-7)N,`
Mahendra.s mass = m = 75 kg.
According to Newton.s second law, the acceleration produced by the force on
Mahendra = m = 75 kg.
`a=(F)/(m)=(4.002xx10^(-7))/(75)`
`5.34xx10^(-9)m//s^(2)`
Using Newton.s first equation, we can calculate Mahendra.s velocity after 1 s,
Newton.s first equation of motion is v = u + at, As Mahendra is sitting on the bench, his initial velocity is zero (u = 0)
Assuming the bench to be frictionless,
`V=0+5.34xx10^(-9)xx1`
`=5.34xx10^(-9)m//s`
Mahendra.s velocity after 1 s will be `5.34xx10^(-9)m//s`
