A 30 g block sits at the center of a turntable that rotates at 65 rpm. A compressed
spring shoots the block radially outward from the center along a frictionless groove
in the surface of the turntable. Calculate the turntable's angular speed when the
block reaches the outer edge. Treat the turntable as a solid disk with mass with mass
200 g and diameter 30.0 cm. Express your answer in revolutions per minute.

A uniform rod is set up so that it can rotate about an axis at perpendicular to one of its ends. The length and mass of the rod are 0.759 m and 1.31 kg, respectively. A force of constant magnitude F acts on the rod at the end opposite the rotation axis. The direction of the force is perpendicular to both the rod's length and the rotation axis. Calculate the value of F that will accelerate the rod from rest to an angular speed of 6.69 rad/s in 8.49 s. F =

A solid sphere with a mass of 2.00 kg and a radius of 50.0 cm is rolled towards the bottom of a ramp. When the sphere reaches the bottom of the ramp, a point halfway between the center of the sphere and the edge of the sphere has a tangential speed of 1.50 m/s. How high up the ramp will the sphere roll?

A solid cylinder of mass 4.6 kg and radius 0.6 m starts from rest at the top of a ramp, inclined 21°, and rolls to the bottom without slipping. (For a cylinder I = 0.5MR2) The upper end of the ramp is 7 m higher than the lower end. Find the linear velocity of the cylinder when it reaches the bottom of the ramp? (g = 9.8 m/s2)
A uniform disk of mass 7 kg and radius 0.2 m is free to rotated about an axis perpendicular to its center. A constant force of size 146 N acts at the edge of the disk, in a direction tangent to that edge. The force acts until the disk has completed 169 full rotations. What is the angular momentum of the disk after those rotations are complete, in kg m2/s? It could be useful to you to know that the rotational inertia of a uniform disk is 1/2 M R2. (Please answer to the fourth decimal place - i.e 14.3225)
