A compact disk starts from rest and accelerates to its final angular velocity of 3.50 rev/s in 1.50 s. Find the disc's average angular acceleration in revolutions per second squared and in radians per seco

An electric drill starts from rest and undergoes uniform angular acceleration for a period of 0.130 s until it turns at a rate of 2.35 x 10 rev/min. (a) What is the drill's angular acceleration (in rad/s)? (Enter the magnitude.) rad/s? (b) What is the angle (in radians) through which the drill rotates during this period? (Enter the magnitude.) rad

As shown in the figure below, wheel A has a radius of 10 cm and is attached by a belt to to wheel C which has a radius of 25 cm.  The angular speed of wheel A is increased from rest at a constant rate of 1.1 rad/s2(α).  Determine the the time needed for wheel C to reach an angular speed of 100 rev/min assuming the belt does not slip.  The linear velocity of the belt must be the same so αArA=αCrC.  The relationship between angular acceleration and angular speed is ω=αt.  2pi rad = 1 rev.  Don't forget to convert to consistent units.

A 2.00-cm radius disk has an angular acceleration of
