If a Ferris wheel starts from rest and accelerates up to an angular velocity of 1 revolution every 10 seconds, what is the average angular acceleration if this acceleration takes 1 minute? How many revolutions does the Ferris wheel undergo in this time?

1 revolution = 2 * pi radians
angular speed = 2 * pi / 10seconds = 0.63 rads per sec
1 minute = 60 seconds so acceleration
= 0.63 / 60 = 0.01 rads / sec²

unique angular velocity ? = 17 rad/s Angular displacement in the time of combating time ? = 5.9 rad combating time is t = 2?/ ? = 2*(5.9 rad)/(17 rad/s) = 0.69412 s Angular acceleration (deceleration) is ? = ?/t = (17 rad/s)/( 0.69412 s) = 24.40 9 rad/s² -
