A 40.3-cm diameter disk rotates with a constant angular acceleration of 2.50 rad/s2. It starts from rest at t = 0, and a line drawn from the center of the disk to a point Pon the rim of the disk makes an angle of 57.3° with the positive x-axis at this time.
(a) Find the angular speed of the wheel at t = 2.30 s.
rad/s
(b) Find the linear velocity and tangential acceleration of P at t = 2.30 s.
linear velocity . m/s
tangential acceleration m/s2
(c) Find the position of P (in degrees, with respect to the positive x-axis) at t = 2.30s.

Two satellites are in circular orbits around a planet that has radius 9.00*10^6 m. One satellite has a mass 68.0 kg, What is the orbital speed of the second satellite
A 270 ball and a 520 ball are linked by a 50.0-cm-long massless, rigid rod. The structure rotates about its center of mass at 120 rpm. What is its rotational kinetic energy.
Assume that the rod is held at rest horizontally and then released. (Throughout the remainder of this problem, your answer may include the symbol, moment of inertia of the assembly, whether or not you have answered the first part correctly.)
