Q3. A woman rides on a Ferris wheel of radius 17 rm m that maintains the same speed throughout its motion. To better know physics, she takes along a digital bathroom scale (with memory) and sits on it. When she gets off the ride, she uploads the scale readings to a computer and creates a graph of scale reading versus time. Note that graph has a minimum value of 519 rm N and a maximum value of 666 rm N.
