A wheel has an initial angular velocity of 30rev/min and then experiences an angular deceleration of 0.25rad/s2 over 30s.  What is the new angular velocity of the wheel?

If a flywheel is initially moving at an angular velocity Wi = 10 rad/s and accelerates to a final angular velocity Wf = 400 rad/s in a time of 3 seconds, calculate: a.) the angular acceleration (alpha = a) b.) the angular displacement (theta)

What constant angular acceleration is required to reduce an object's angular velocity from 36.7 rad/s to 12.6 rad/s over 11 revolutions?

A merry-go-round (treat as uniform disk) with mass of 65 kg and outer radius of 3.1meters, is rotating at 6 rad/s. An initially stationary child grabs on to the outer edgeand thereafter, moves with the merry-go-round. The child has mass 25 kg. What isthe final angular velocity of the merry-go-round in rad/s?

A cyclist starts from rest and pedals so that the wheels make 8.00 revolutions in the first 8.10 s. What is the angular acceleration of the wheels (assumed constant)?

The angular acceleration of a wheel is a = 6.0t“ - 7.0t2, with a in radians per second-squared and t in seconds. At time t = 0, the wheel has an angular velocity of +6 rad/s and an angular position of +4 rad. Write expressions for (a) the angular velocity (rad/s) and (b) the angular position (rad) as functions of time (s). (a) Number t5. i t3+ i Units (b) Number i t6- i t4+ i t+ i Units

What is the initial angular velocity of an object if it has a final angular velocity of -9.62rad/s, it has an angular acceleration of -1.35rad/s/s, and it rotates for a time of 0.64s? ωo =  _____

A playground merry-go-round has a mass of  133kg and a radius of  1.82m and it is rotating with an angular velocity of  0.424rev/s. What is its angular velocity after a 29-kg child gets onto it by grabbing its outer edge? The child is initially at rest.

What is the final angular position of an object if it has an initial angular position of -19.49 rad relative to some zero position, an angular acceleration of 1.2 rad/s/s, an initial angular velocity of 9 rad/s, and it rotates for a time of 3.24s?
