The three blocks of masses 10.0 kg, m = 4.70 kg, and 3.00 kg are connected by light strings that pass over frictionless pulleys as shown in Figure P4.69. The acceleration of the 4.70 kg block is 1.80 m/s2 to the left, and the surfaces are rough.
(a) Find the tension in each string. (Assume the same Âµk for both blocks in contact with surfaces.)
T1: N
T2: N
(b) Find the coefficient of kinetic friction between blocks and surfaces.
