6. A reflector is fastened to the front wheel of a bicycle 20 centimeters from the center of the wheel. The diameter of the wheel and inflated tire is 70 centimeters. If the bike is traveling at 10 km/h, express the height of the reflector above the ground as a function of time. Assume that at t = 0 seconds, the reflector is at its highest point. 2 DEBAMINÉ nits ANbvue VELOCIY OE THE WITE EL 70 cm DETERM (NE TtE PERICO Ot ntE WAVE. 13] uS E THE os I TION GF THE REFLECTON As TiHE WhteEL SIZE TO OBDADN OS CIUSTEN
