Question

objects of masses m1=4 kg and m2=9kg are connected by a light string that passes over a frictionless pulley. the object m1 is held at rest on the floor and m2 rests on a fixed incline of delta=40 degrees. the objects are released from rest and m2 slids 1.00 m down the inclinein 4.00 seconds. determine a) the acceleration of each object. b)the tension in the string. and c)the coefficient of kinetic friction between m2 and the incline.
