A bowling ball of mass 7.5 kg and radius 9.0 cm rolls without slipping 10 m down a lane at 4.3 m/s. Calculate the tangential acceleration of the bowling ball. (Iball = 2/3 Mr2)

A wind turbine is rotating counterclockwise at 0.78 rev/s and slows to a stop in 21 s. Its blades are 27 m in length. (a) What is the angular acceleration of the turbine (in rad/s)? (Indicate the direction with the sign of your answer.) |rad/s2 (b) What is the centripetal acceleration (in m/s2) of the tip of the blades at t = 0? (Enter the magnitude. Round your answer to at least two decimal places.) m/s? (c) What is the magnitude (in m/s) of the total linear acceleration of the tip of the blades at t = 0? (Round your answer to at least two decimal places.) m/s2 What is the angle that this total linear acceleration vector makes with the centripetal acceleration vector? (Enter the magnitude of the smallest such angle in degrees.)

A compact disk of diameter 8 cm starts from rest and speeds up uniformly to 2 rev/s in 4.0 seconds.  What is the tangential acceleration of a point on the outer rim of the disk moving at 3 rev/s?

A cylinder 37.0 cm in diameter is at rest initially. It is then given an angular acceleration of 0.068 rad/s^2. Find the angular velocity at 5.26 s. Give your answer in rad.
