At time tj, the kinetic energy of a particle is 35.0 J and the potential energy

Question

At time tj, the kinetic energy of a particle is 35.0 J and the potential energy of the system to which it belongs is 8.00 J. At some later time tf, the kinetic energy of the particle is 19.0 J. If only conservative forces act on the particle, what are the potential energy and the total energy at time tf? potential energy J total energy J If the potential energy of the system at time tf is 21.0 J, are there any nonconservative forces acting on the particle? No. The gain in potential energy and the loss in kinetic energy of the system are equal. No. The loss in potential energy and the gain in kinetic energy of the system are equal. Yes. The loss in potential energy and the gain in kinetic energy of the system are not equal. Yes. The gain in potential energy and the loss in kinetic energy of the system are not equal.
