Solve using any method you would like, but show your work. Suppose we were considering the Atwood’s machine pictured at right. A block of mass M1 = 1.5 kg is on a surface with coefficient of friction µ = 0.10, which is tilted at an angle α = 30º. A second block of mass M2 = 3.5 kg is hanging vertically. The two blocks are connected via an ideal massless string that passes over a pulley of mass mp = 0.55 kg and radius rp= 7.5 cm which can be treated as a solid disk. At time t0 block 2 is released from rest and it begins to fall.

a. Determine the magnitude of the friction force. Show your work

b. Determine the speed of the blocks when block 2 hits the floor, 0.35 m below where it starts. Show your work

c. After block 2 hits the floor, how much farther will block 1 slide up the incline before coming to rest? Show your work (hint, once block 2 hits the floor the tension in the string goes to zero – will it have any effect anymore?)

Show all your work as you go through any calculations. Thank you! 1. Suppose a firm uses labor and capital to produce boat shoes. (a) (6 points) When presenting the optimization problem for the firm, assume that labor is put on the horizontal axis and capital on the vertical axis. If the marginal technical rate of substitution between labor and capital is currently 8 capital per worker, what does this mean? Interpret the number itself and explain fully. (b) (4...

Q. I would like you to use a fixed point method to solve the positive real quadratic root of 4 by solving h(x) = x^4 − 4 = 0. The standard method manipulates h(x) = 0 into g(x) = x so that the iterative scheme becomes xn+1 = g(xn). The iterative scheme will converge to the required solution if the root is in the interval defined by |g '(x)| < 1 (i) We begin by adding x to both sides...
