2.2 Two objects are connected by a light string that passes over a frictionless pulley, as shown in the figure below. If the incline has a kinetic friction between mass m2 and the table, and if m1 = 2 kg, m2 = 7 kg, and θ = 55∘, draw free-body diagrams of both objects and (a) Derive the equation for acceleration of this motion. Calculate:- (b) the accelerations of the objects, (c) the tension in the string, (2) (d) the speed of each object 4 s after being released from rest. (2) (e) the kinetic energy of the system after 4 s. (4)
