ROTATIONAL KINEMATICS 1. A solid circular disk has the following measurements: Radius = 23 cm Mass = 1.25 kg Thickness = 5 cm The disc is set spinning at a constant rate. It makes 3.5 revolutions per second. (a) What is the rotational (angular) velocity? (b) What is the linear velocity of a point on the disk at half the radius? (c) If the disk spins for 5 seconds, what is the rotational displacement? (d) If the disk spins for 5 seconds, what is the linear displacement of a point on the rim? (e) From its motionless beginning, it took 14 seconds to achieve the constant rate. What is the rotational (angular) acceleration? (0 What is the torque that achieved the acceleration in (e)
