A woman rides on a Ferris wheel of radius 16m that maintains the same speed throughout its motion. To better understand 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. (Figure 1) Note that the graph has a minimum value of 510N and a maximum value of 666N . The acceleration due to gravity, g=9.80m/s2.
Figure

Mass of the woman is 60 kg and constant speed of the wheel is 4.56 m/s

Explanation:

The maximum reading of the scale is when wheel is at the bottom position

So it is given as

Similarly the minimum value is when she is at the top position of the wheel

So it is given as

so from above two equations we have

also the speed of the wheel is given as

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.
