Question 4 (12 marks) Consider the diagram for question 4. There is no friction. The mass of X is 7.86 kg and the mass of Y is 1.66 kg. The incline of the ramp is 39.7 degrees. a) (4 marks) Calculate the acceleration of the system. Include the direction. b) (4 marks) Calculate the tension in the rope connecting the X and Y blocks. c) (4 marks) Calculate the new mass of block Y, keeping block X the same, that acceleration is zero. Bonus) If there was friction, then there would be a range of masses block Y can be, such that the acceleration would be zero, not just one number. Explain why this is the case.
