Two blocks, of weights 3.6N and 7.2 N,are connected by a massless string anf slide down a 30 inclinea plane.
The coefficient of kinetic friction between the lighter block and the plane is 0.10 the lighter block leads, and the coefficient of kinetic friction between the heavier block and the plane is 0.20. Assuming the lighter block leads,find
(a) the magnitude of the acceleration of the blocks, and
(b) the tension in the taut string
