You bicycle along a straight flat road with a safety light attached to one foot. your bike moves at a speed of 30 km/hr and your foot moves in a circle of radius18 cm centered 28 cm above the ground, making one revolution per second. (a) find parametric equations for x and y which describe the path traced out by the light, where y is distance (in cm) above the ground and x the horizontal distance (in cm) starting position of the center of the circle around which your foot moves. assuming the light starts cm above the ground, at the front of its rotation. x(t)= y(t)= (b) how fast (in revolutions/sec) would your foot have to be rotating if an observer standing at the side of the road sees the light moving backward? rotate at ? revolutions/second.
