A person holds up a plank so that it makes an angle θ with the horizontal ground. A block of mass m = 7 kg is able to remain at rest on the plank because of friction. The coefficients of friction between the block and the plank are μs = 0.71 and μk = 0.38. 1) At first, the person raises the plank to an angle θ = 25∘. What is the maximum possible amount of static friction that the plank can exert on the block at this angle? N Submit 2) What is the magnitude of the friction force that the plank exerts on the block for this situation? m/s2 Submit 3) In this situation, what is the magnitude of the acceleration of the block? m/s2 Submit 4) What is the maximum angle that the person can lift the plank to before the block starts to slide downward? degrees Submit 5) Right when you get to this maximum angle, if you even go barely a little bit further, the block starts to slide downwards. If the person keeps the plank held at this maximum angle while the block starts to slide downward, what will the acceleration of the block be?

The range of a charged particle in matter is the total path length accumulated until it stops. This is a function of its initial energy. Using the Bethe-Bloch equation use any software (such as Mathematica, Mathlab, C/C++, any other language) that allows you to perform numerical calculations on differential equations to estimate the range in water of a proton of 200MeV initial kinetic energy.

1. You complete an experiment by rolling a six sided fair die. The following events are defined: (1) A = {1,3,4}; (2) B = {2,4,6}; (3) C = {3}; (4) D = {3,5,6}; (5) E = {1,3,5}; (6) F = {5,6}. Determine the following events. (a) $A \cup D$. (b) $A \cap D$. (c) $B \cap E$. (d) $A^c$. (e) $B^c \cap C$. (f) $(B \cup C)^c$. (g) State whether the following statements are true of false. If false, state why it is false. (i) A and C are mutually exclusive. (ii) A and F are mutually exclusive. (iii) $F \subset A^c$. (iv) $F \subset E$.

2. An audio signal m(t) is to be digitized using a non-uniform PCM encoding scheme. The bandwidth of the signal is 10 KHz, and the signal is to be quantized using a uniform quantization scheme for each of two ranges of the signal but with a different step size. Let mp = max |m(t)| be the peak value of m(t), and let ms = m(kT) be a sample of m(t). If |ms| ? mp/2 then the quantization error should be less than 0.1% of the peak, mp, otherwise the quantization error should be less than 0.4% of the peak. a) Determine a quantization scheme by listing all the threshold values; that is, specify the characteristics of the quantizer by giving the the output quantized level versus the input analog voltage level for each value of the sample. b) Assign a unique binary code to the quantized levels. What is the number of bits per sample? c) Determine the bit rate for the digitized speech signal assuming a 20% oversampling rate in order to facilitate the filtering during signal reconstruction.
