A body starts from rest on a smooth horizontal surface under

A body starts from rest on a smooth horizontal surface under the action of a constant horizontal force F and a resistance force FR kv where k is a positive constant and v is instantaneous speed Choose the correct option as a function of time t t 0 u 0 m 0 F www F A Velocity achieved by body at time t is V L1 e v 1 e m k B Curve between velocity and time t and that between power of force F and time t are both straight line C Power of force F increase continuously and becomes constant finally after long time D Rate of change of power of force F decreases continuously and becomes zero finally after long time
