Find out a the coefficient of kinetic friction between m2, Ask an Expert

Academics

masses m1= 4.00kg and m2= 9.00 kg are connected by a light string that passes over a frictionless pulley. m1 is held at rest on the floor and m2 rests on a fixed incline of theta= 40.0 degrees. the masses are released from rest, and m2 slides 1.00 m down the incline in 4.00s. determine (a) the coefficient of kinetic friction between m2 and the incline, (b) the acceleration of each mass, and (C) the tension in the string.
