I HAVE A TIME LIMIT

Question 16 A 10 kg mass (Mass A) lays on an inclined plane as shown in the image below. Mass A is connected to an unknown Not yet hanging mass (Mass B) by a thin rope passing over a frictionless pulley. You may ignore the mass Time left 2:58:46 answered Marked out of 7.00 Flag question A B The ramp angle (0) is 30 and the coefficient of friction between Mass A and the ramp is 0.25. Calculate the SMALLEST value of Mass B that will cause Mass A to accelerate UP the ramp. Show all work done to solve this problem. You MUST include free-body diagrams in your answer, and please show me your formulas and any units in your calculations. 1 mark for Free-Body-Diagram 4 marks for Net-Force Equations and Calculations 2 marks for Calculating the Minimum Value for Mass B Paragraph B ENormal e Tension (T ) m A friction X Tension (T ) m B MB
