Question

At time ti
, the kinetic energy of a particle is
41.1 J and its potential energy is 11.9 J. At
some later time tf , its kinetic energy is 18.2 J and 34.8 J for potential energy
If the potential energy at time tf is 7.54 J,
what is the work done by the nonconservative
forces acting on the particle?
Answer in units of J.
