A wheel rotates in the clockwise (positive) direction and has no friction. The wheel is allowed to rotate for 4 seconds, then, at t=4s, a brake is applied so that the wheel slows down at a rate of alpha. At t=4s, alpha is zero but increases in magnitude linearly by 2 rad/s/s every second. The wheel stops in 4 s (at t=8s). Caloulate the initial angular speed of the wheel, and draw (with axis labels and scales) the omega vs. time and alpha vs. time (with correct signs) of the wheel for the 8 seconds described.

(a) We choose $x = 0$ to be the initial location of the first player, and $t = 0$ to be the instant when this player starts to chase his opponent. At this time, the opponent is $(1.90 \text{ s})(5.0 \text{ m/s}) = 9.5 \text{ m}$ in front of the first player. We are given that the first player accelerates uniformly at $0.37 \text{ m/s}^2$. At time $t > 0$ the displacements of the first player and his opponent from the origin are $x_{player} = (x_0)_{player} + (v_0)_{player}t + \frac{1}{2}a_{player}t^2$ $= 0 + 0 + \frac{1}{2} \left(0.37 \text{ m/s}^2\right)t^2$ and $x_{opponent} = (x_0)_{opponent} + (v_0)_{opponent}t + \frac{1}{2}a_{opponent}t^2$ $= \left(9.5 \text{ m}\right) + \left(\boxed{\text{ }} \text{ m/s}\right)t + 0.$

d) A South African manufacturer of BMW cars offers a model in one of three colors: Blue, Red, or Black. In his report, the manufacturer indicated that of the first 1000 cars sold, 400 were of color Blue. With this information from the manufacturer, perform a test at $\alpha = 1\%$ and conclude whether or not the customers do have more preference for BMW cars which have Blue color? Show all necessary steps and justify your answer. (6)

(18pts) 1. Concepts Understanding (6 points each) (1.1). It is the principle of locality that gives us a chance to overcome the long latency of memory access. Please explain what are temporal locality and spacial locality, and give an very simple example (in the area of computer architecture) to illustrate the point.
