Two blocks,AandB(with mass40kg and115kg, respectively), are connected by a string, as shown in the figure below. The pulley is frictionless and of negligible mass. The coefficient of kinetic friction between blockAand the incline is

_k=0.30.

Determine the change in the kinetic energy of blockAas it moves fromto, a distance of19m up the incline (and blockBdrops downward a distance of19m) if the system starts from rest.
