4. On a frictionless pulley, a 4.0 and 0.0 kg mass are connected as shown on a ramp 1with a slope of 30 degrees. The coefficient of kinetic friction on the ramp is 0.18. a) Draw the FBDs of both masses. {1 pt} b) Determine the acceleration of the masses once they begin to slide. Show your work.(2 pts) c} Determine the tension in the rope. Show your work.(1 pt) d) lfthe rope breaks then the 4.0 kg mass is 3.0 m from the bottom of the ramp: howr long will it take for the mass to slide down? Include a new free body diagram and assume the sliding mass starts from rest. Show your work.(2 pts)
