A wind turbine whose blades are 16 m is rotating counterclockwise at a rate of 0.88 rev/s. It uniformly slows down until it stops after rotating for 6.4 s. What is the magnitude of the linear acceleration at t= Os? Round your answer to 2 decimal places.

A ceiling fan is turned on and reaches an angular speed of 111 rev/min in 23 s. It is then turned off and coasts to a stop in 47 s. In the [t1+t2] s of rotation, through how many revolutions did the fan turn?

A flywheel is rotating at 36.5 rev/s.What is the total angle, in radians, through which a point on the flywheel rotates in 29.7 s?

Afham is riding a merry-go-round. He is 5 meters from the center and the merry- go-round completes three revolutions per minute. Find the centripetal acceleration acting on Afham. Answer (0.5rt) /5 m s-2 (0.5t) /5 rad s-2 0.49 m s-2 1.57 rad s-1

A bear pushes, with a constant force, a circular rock with a radius of 7.2 m from rest.  The rock rotates with a  acceleration of 4.0 m/s2 at t = 5.0 s. What is its tangential acceleration at t = 5.0 s. {ac=r?2    at=r?}

A particle is moving in a circle of radius R. At t = 0, it is located on the x-axis. The angle the particle makes with the positive x -axis is given by 0 = At² + Bt³ What is the magnitude of the tangential acceleration, atan of the particle at a time t > 0? Express your answer in terms of R, t, A, and B as needed. What is the magnitude of the radial acceleration, larad of the particle at a time t > 0? Express your answer in terms of R, t, A, and B as needed.

A light rod is 88 cm long. Its top end is pivoted on a low-friction horizontal axle. The rod hangs straight down at rest with a small massive ball attached to its bottom end. You strike the ball, suddenly giving it a horizontal velocity so that it swing around in full circle. What minimum speed (m/s) at the bottom is required to make the ball go over the top of the circle?   Round your answer to 2 decimal places.
