A force acting on a particle of mass m is given by F=kxxwhere k is a constant. The particle is injected into this field at the origin with speed v0at time t=0. The position x of the particle (as a function of t) is given by
A) X =√mv/k. cot {kv/m.T}
B) X = √2mv/k. tan {kv.m.t}
C) X = √2mv/k tan {kv/2m. t}
D) X = √mv/2k. tan { kv/m. t}
