A particle of mass 'm' is at rest the origin at time t =0. It is subjected to a force F(t) = F_(0)e^("bt") in the X-direction

A block of mass 2 kg is free to move along the x -axis. It at rest and from t = 0 onwards it is subjected to a time-dependent force F(t) in the x direction. The force F(t) varies with t as shown in the figure. The kinetic energy of the block after 4.5 seconds is
