Two blocks, A and B (with mass 60 kg and 130 kg, 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 block A and the incline is
= 0.24. Determine the change in the kinetic energy of block A as it moves from © to O, a distance of 21 m up the
incline (and block B drops downward a distance of 21 m) if the system starts from rest.
