A rod AB moves in a plane such that the end B describes a circle if center C and radius a with uniform angular velocity ω and the end A moves in a straight line passing through C. Prove that if AB= a, the motion of A is simple harmonic motion. Find the amplitude and the periodic time of this motion.

Astudent draws two parabolas on graph paper. both parabolas cross the x-axis at (-4, 0) and (6,0). the y-intercept of thefirst parabola is (0, –12). the y-intercept of the second parabola is (0-24). what is the positive difference between the avalues for the two functions that describe the parabolas? write your answer as a decimal rounded to the nearest tenth.
