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
\(F = {F_0}\left[ {1 - {{\left( {{{t - T} \over T}} \right)}^2}} \right]\)
Where F0 and T are constants. The force acts only for the time interval 2T. The velocity v of the particle after time 2T is :
