Question

11. Mastering Michelle's Maniacal Mystery Machine In the scenario depicted below, all surfaces are frictionless. The masses are given as Mi, M2, Ma as on the diagram. Mass Mi is free to slide on a surface at rest relative to the surface of the Earth (like a smooth table). Let the positive x-direction point to the right, and let the positive y-direction point upward. Analyze this system from a reference frame at rest relative to the surface on which block 1 is free to slide this is an inertial frame a. For each of the objects 1,2, 3, name any other objects that are exerting a force on it. For each of these forces, if the direction of the force is known, assign a variable to the magnitude of this force. If the direction of the force is unknown, assign a variable to nonzero the component (s) of this force. M2 M, b. Write down an expression for the sum of the forces on each object. c. Write down Newton's Second Law for each object, and count the number of equa- tions and unknowns you have. d. Determine an equation relating the accelerations of blocks 1 and 3 in the direction. equa- tion relating various components of the accelerations of the three blocks. f. Optional / difficult! Solve for the acceleration of block 1 in terms of the masses and g. Check the units of your expression, and try to determine if there are any limiting cases you can check as well.

Explanation / Answer

a)The force on M1 is due to its weight along y direction and normal reaction in upward direction. Also force due to weight of M2 and M3.

On M2 the force F2 is due to the string in x-direction ,due to its weight in y direction and normal reaction due to

M1 in upward direction and on M3 there is force F3 due to string in upward direction and due to its weight in downward direction and normal reaction due to M1 in upward direction.

b) F1+F2+F3=(M1+M2+M3)g as external force

c)
