1. The figure shows an 8 Kg stone at rest on a spring. The spring, at the stage shown in the figure, is found to be compressed 5 cm by the stone. 1A (5 points) Calculate the spring constant $k$ of the spring. 1B (5 points) The stone is pushed down an additional 15 cm and released. What is the elastic potential energy of the compressed spring just before that release? 1C (15 points) The stone moves from the released point to its maximum height. What is the maximum height measured from the released point? 1D (10 points) Calculate the work done by the gravitational force when the stone moves from the released point to its maximum height. 2.

A modern digital wireless communication system transmits at a center frequency of 1.9 GHz and has a data rate of 1.2288 Mb/s. Assume that there are two signal paths that differ in amplitude by 1 dB and in phase by Ï†2 - Ï†1 = Ï€/4. The receiver is moving at 60 mph and the signal arrives at -5Â° and 85Â° with respect to the direction of travel. a. What is the Doppler spread? b. What is the period of a fading cycle? c. Is the fading fast or slow with respect to the signal? How fast would the receiver have to be moving to experience fast fading? (Assume that each symbol of the signal represents 1 bit)

To find the new coordinates of a triangle that has been rotated 90° clockwise about the origin, you multiply the vertex matrix by the rotation matrix $\begin{bmatrix} 0 & 1 \ -1 & 0 \end{bmatrix}$. If the coordinates of $\triangle ABC$ are A(5, 7), B(-4, 3), and C(-6, 8), use this information to determine the new coordinates for $\triangle A'B'C'$ after it has been rotated 90° clockwise about the origin. A'(-7, 5), B'(3, 4), C'(8, 6) A'(-7, 5), B'(-3, -4), C'(8, 6) A'(-7, 5), B'(-3, -4), C'(-8, -6) A'(7, -5), B'(3, 4), C'(8, 6)
