1.	A particle moving in the positive x-direction has initial v_(0). The particle undergoes retardation kv^(2), where it its instantaneous velocity. The velocity of the particle as a function of time is given by
Answer» `v=v_(0)//(1+kv_(0)t)` `v=(2v_(0))/(1+kt)` `v=(v_(0))/(kt)` `v=(v_(0))/((1+k^(2)v_(0)^(2)t))` ANSWER :A
