Aparticle of mass m sits at rest at x = 0. at time t = 0 a force given by f = fe^(-t/t) is applied in the +x direction; f and t are constants. when t = t the force is removed. at this instant when the force is removed, (a) what is the speed of the particle and (b) where is it?

This is what i found on google “kinetic energy. energy is transferred from one object to another when a reaction takes place. energy comes in many forms and can be transferred from one object to another as heat, light, or motion, to name a few. this energy would be in the form of motion, with the person lifting the blue ball to a higher level.” i hope this you
