A particle of mass M orginally at rest is subjected to a force whose direction is constant but magnitude varies with time according to the relation F=F0[1−(t−T/T)²]
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 :
A 2F0T/M
B F0T/2M
C 4F0T/3M
D F0T/3M
