engineering team is to stop a water turbine for maintenance. During the shutdown process, the angular acceleration d of the turbine is given by: a=-0.02w, where a is rad's and the angular velocity w is in rad/s. Calculate how many revolutions the turbine rotates during the period when it slows from 10000 rev/min to 1000 rev/min.

Nilo.p A baseball bat is swung with an angular velocity of 500°/s and has a radius of 1.2m. What is the linear velocity of the baseball bat?

As you finish listening to your favorite compact disc (CD), the CD in the player slows down to a stop. Assume that the CD spins down with a constant angular acceleration. If the CD rotates clockwise at 500 rpm (revolutions per minute) while the last song is playing, and then spins down to zero angular speed in 2.60 s with constant angular acceleration, what is α, the magnitude of the angular acceleration of the CD, as it spins to a stop? A grinding wheel 0.21 m in diameter rotates at 2600 rpm . Calculate its angular velocity in rad/s. What is the linear speed of a point on the edge of the grinding wheel? What is the acceleration of a point on the edge of the grinding wheel? A small rubber wheel is used to drive a large pottery wheel. The two wheels are mounted so that their circular edges touch. The small wheel has a radius of 1.7 cm and accelerates at the rate of 6.9 rad/s2 , and it is in contact with the pottery wheel (radius 28.0 cm ) without slipping. Calculate the…

A uniform disk with radius 0.800 m and mass 30.0 kg rotates in a horizontal plane on a frictionless vertical axle that passes through the center of the disk. The angle through which the disk has turned varies with time according to 0(t) = (1.10 rad/s)t + (6.30 rad/s²)t². Part A What is the resultant linear acceleration of a point on the rim of the disk at the instant when the disk has turned through 0.100 rev?
