A Ferris wheel is rotating with an angular speed of 0.240 rad/s. An angular acceleration of 0.030 rad/2 is applied while the Ferris wheel turns through an angle of 18.8 rad. What is the angular speed after it has turned through that angle? Select one: O a. O b. C. O d. 1.37 rad/s 1.19 rad/s 0.487 rad/s 1.09 rad/s

A golfer is hitting a shot, the angular velocity of her club is zero at the top of the backswing and 30 rad/s at the bottom of the downswing just before impact with the ball. If the downswing lasts 0.30 s, what is the average angular acceleration of the club during the downswing? A. 100 rad/s^2 B. 10 rad/s^2 C. 100 deg/s^2 D. 30 rad/s^2  pick one answer only this is for biomechanics

A person sits in a chair that is free to rotate without friction. Intheir hands, they hold two masses: Mass m1 = 5.0 kg a distance r1 = 0.35m  from their body and mass m2 = 3.0 kg a distance r2 = 0.75 m from their body. a. At what distance r1 should the person hold mass m1 if they want to change their rotation speed from w1 = 8.0 rad/s to wf = 5.0 rad/s? b. What is the new moment of inertia about the vertical axis when m1 is held at this new distance?

When a fan is switched from medium to high the fan blade accelerates from 12.0rev/sec to 15.Orev/sec. During this time it rotates through 125rad. What is the fan blade's angular acceleration? O 2.32 rad/s? O 11.8 rad/s? O 13.8 rad/s? O 1.32 rad/s? O 12.8 rad/s2 O 0.324 rad/s2
