A particle of mass {M} originally at rest is subjected to a force whose direction is constant but magnitude varies with time according to the relation {F}={F}_{0}[1-({{t}-{T}}/{{T}})^{2}] Where {F}_{0} and {T} are constants. The force acts only for the time interval 2 {T}. The velocity {v} of the particle after time 2 {T} is : [27 Jul 2021 Shift 2]
