What is kinetic energy of ball when it reaches final positon

Reference no: EM13986107

A ball with the mass m is released from rest and is acted upon by a net force F=-ax². The ball starts from rest at an initial position xi and moves under the influence of the force to a final position x_f. What is the kinetic energy of the ball when it reaches final positon x_f.
