Aperson rides a bicycle down the street. the position of a reflector attached to a point on the rim of one wheel is r- (0.5m) (cos(8.8t) - 8.8t)i + sin(8.8t)j where i is the unit vector pointing in the x-direction (horizontal) and j is the unit vector pointing in the y-direction (vertical), and t is measured in seconds. the position of the reflector in the formula is measured with respect to a stationary point on the ground the center of the wheel a stationary point at the same height above the ground as the center of the wheel hint: remember that the sine of an angle has a value between -1 and 1. can the reflector ever sink below the ground? what is the velocity of the reflector at the instant when it touches the ground? zero 4.4j

Assume a parabolic reflector is illuminated such that the edges of the reflector see 9 db less power than the center of the reflector. the system operates at 18 ghz and has a round reflector diameter of 1 m and a focal length of 2 m. estimate the gain of this horn/reflector combination (assume the dish is uniformly illuminated to the 3 db diameter and stops there)
