Textbook Question
Chapter 2.2, Problem 1cT
Is the magnitude of the force exerted on system A by system B greater than, less than, or equal to the magnitude of the force exerted on system B by system A? Explain.
Would your answer change if the hand were pushing system B to the left instead of pushing system A to the right? If so, how? If not, why not?

(Figure 1)Block 1, of mass m1, is connected over an
ideal (massless and frictionless) pulley to block 2, of
mass m2, as shown. Assume that the blocks accelerate
as shown with an acceleration of magnitude a and that
the coefficient of kinetic friction between block 2 and the
plane is μ.
Find the ratio of the masses m1/m2.
Express your answer in terms of some or all of the variables a, μ, and θ, as well as the magnitude of the free-fall
acceleration g.
Please don't copy any other solution, You must have to include a free body diagram.
Given the following information, how would you find the magnitude of the acceleration of the system. Express youranswer in terms of known quantities such as m1, m2, theta, k, xs, x0, and g.
"A ball of mass m1 and block of mass m2 are attached by a lightweight cord that passes over a frictionless pulley of negligible mass, as shown in the figure below. The block lies on a smooth plane inclined at an angle 'theta'. The ball is attached to a spring whose spring constant is k and equilibrium position x0. The spring is then stretched so it measures a length xs. You may use the fact that the force due to a spring is opposite the stretch and equal to −kΔxstretch. The system is then released. You can assume that the acceleration due to gravity is given as g, and use the consistent coordinate system specified for each object."
