Answer :
(i) Initial kinetic energy=
final Kinetic energy (after coming to stop) = 0
(ii) Now let’s figure out the energy that’s being wasted on friction on the work done by the kinetic friction. Work done by the friction is the negative of the work done on the object. Therefore, Work done by the kinetic friction,
