Question

A Ferris wheel rotates at an angular velocity of 3.9×10−2 radians/sec. At t= 0 your friend Seth is at the very top of the ride.

What is Seth’s angular position at t = 3.4min measured counterclockwise from the top? Give your answer as an angle in degrees between 0 and 360 degrees

Answer 1

Come to think about I have no friend by the name Seth..

However  3.4min  later Seth would have traveled

Angle=wt =  3.9×10^−2  x 3.4 x 60=795.6

Number of full turns = 795.6 /(2pi)=126.6236.... turns

Angle relative to top most position = 0.623.. x (2x pi)=3.92 radians  or

Deg= 3.92 (180/pi)=224.5 deg  from top most position
