4. A light rope is wrapped several times around a large wheel with a radius of 0.500 m. The wheel rotates on frictionless bearings about a stationary horizontal axis, as shown in the figure. The free end of the rope is tied to a suitcase with a mass of 15.0 kg. The suitcase is released from rest at a height "h" above the ground. The suitcase is accelerating with 2 m/s² and the wheel has an angular speed of 8.0 rad/s when it reaches the ground. 4.00 m a) Calculate the height h above the ground where the suitcase is released. b) Find the time it takes for the suitcase to reach to the ground. c) Calculate the moment of inertia of the wheel.

A wheel is rotating about a fixed axis with constant angular acceleration 3 rad/s2. At different moments, its angular speed is 2 rad/s, 0. and +2 rad/s. For a point on the rim of the wheel, consider at these moments the magnitude of the tangential component of acceleration and the magnitude of the radial component of acceleration. Rank the following five items from largest to smallest: (a) |at| when = 2 rad/s, (b)|ar| when = 2 rad/s, (c)|ar| when = 0, (d) |at| when = 2 rad/s, and (e) |ar| when = 2 rad/s. If two items are equal, show them as equal in your ranking. If a quantity is equal to zero, show that fact in your ranking.
