Objects of masses m1 = 4.00 kg and m2 = 9.00 kg are connected by a light string that passes over a frictionless pulley as in the figure below. The object m1 is held at rest on the floor, and m2 rests on a fixed incline of θ = 39.5°. The objects are released from rest, and m2 slides 1.25 m down the slope of the incline in 3.85 s. A triangular structure is oriented such that its base rests upon a horizontal surface, its left side is perpendicular to its base, and its right side forms an incline of angle θ. A pulley is attached to the structure's apex. Two objects are connected by a cord that passes over the pulley. An object labeled m1 is attached to the left end of the cord and hangs such that it is very close to the horizontal surface. A rectangular object labeled m2 is attached to the end of the cord and rests upon the incline. A pale image of m1 is above m1, and a pale image of m2 is farther down the incline than m2. (a) Determine the acceleration of each object. (Enter the magnitude only.) m/s2 (b) Determine the tension in the string. (Enter the magnitude only.) N (c) Determine the coefficient of kinetic friction between m2 and the incline.
