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?

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
