3. Two masses, 4.0 kg and 6.0 kg, are connectedby a “massless" rope over a “frictionless" pulleyas pictured in the diagram. The ramp is inclinedat 30.0° and the coefficient of kinetic friction onthe ramp is 0.18.4.0 kgHx = 0.186.0 kg300а.Draw free-body diagrams of bothmasses.b. Determine the acceleration of thesystem once it begins to slide.c. Determine the tension in the rope.d. If the rope breaks when the 4.0-kg massis 3.0 m from the bottom of the ramp,how long will it take for the mass to slideall the way down? Include a newfree-body diagram and assume thesliding mass starts from rest.TUse the grasp method todetermine the answer
