A Ferris wheel rotates at an angular velocity of 0.26 rad/s. Starting from rest, it reaches its operating speed with an average angular acceleration of 0.034 rad/s2. How long does it take the wheel to come up to operating speed?
Homework Answers
intial angular velocity is wi = 0 rad/sec
final angular velocity is wf = 0.26 rad/sec
angular accelaration is alpha = 0.034 rad/s^2
using kinematic equations
wf = wi+(alpha*t)
0.26 = 0 +(0.034*t)
t = 7.64 sec
