4. On a frictionless pulley, a 4.0 and 6.0 kg mass are connected as shown on a ramp with 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) If the rope breaks then the 4.0 kg mass is 3.0 m from the bottom of the ramp, how 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) 4.
