A block M of mass 2.0kg lies on a rough horizontal table and is connected by a light string over a smooth pulley to a hanging block m of mass 1.5kg. The coefficient of kinetic friction between M and the table surface is μk=0.25. The system is set free from rest.
a. (i) Calculate the magnitude of the frictional force acting on block M while the blocks are in motion.
b. (ii) Determine the acceleration of the system.
c. (iii) Find the tension in the string during the motion.
