Questions 1 through 5 all refer to the same problem Three objects of equal mass, A, B, and C, are released from rest at the same instant from the same height on identical ramps. Objects A and B are both blocks, and they slide down their respective ramps without rotating. Object C rolls down the ramp without slipping. Its moment of inertia is unknown. Objects A, B, and C are made of different materials, thus the coefficients of static or kinetic friction between the objects and their corresponding ramps are not necessarily the same. All three objects are released B A from rest m =m =mc Objects B and C reach the bottom of their ramp at the same instant. Then, at a later instant, object A reaches the bottom of its ramp.Question 1 5 pts Rank the center-of-mass accelerations of objects A, B, and C, according to magnitude, from largest to smallest. If any objects have the same magnitude center-ofmass acceleration, state so explicitly. plain. Question 2 5 pts Rank the net forces exerted on objects A, B, and C, according to magnitude, from largest to smallest. If the magnitude of the net force on any of the objects is the same, state so explicitly. plain your reasoning. Question 3 10 pts Draw and label a (point) free-body diagram for each object (make it clear whether the friction is static or kinetic}. Use the convention used in tutorial for all forces. Draw the FBDs using the format given below (3 boxes side by side) on your own paper and upload your answer as a pdf le. Free-body diagram for object A Freebody diagram Free-body diagram for object B for object C Question 4 5 pts Rank the frictional forces exerted on objects A, B, and C, according to magnitude, from largest to smallest. If the magnitude of the frictional force is the same on any two objects, state so explicitly. Qplain your reasoning: Question 5 5 pts Is the kinetic energy of B greater than, equal to, or less than the kinetic energy of C at the instant when B and C reach the bottom of the ramp? Explain
