An object is spinning about a fixed point o. Its angular position as a function of time is given by the following equation: 00.35 t 8.30 t + 8.00 t - 28.0 where t is in seconds and 0 is in radians. What is the angular velocity (rad/s) of the object at time=5.30 s? Three small spheres with masses m=1.00 kg, m = 2.00 kg and m3 = 3.00 kg are connected together by a light wire and positioned on an x-axis as shown in the figure. Determine the Moment of Inertia (kg-m) for this collection of masses for a rotation about the y-axis if L= 10.0 cm. m 5L 6L m2 m3 x A disk of unknown mass has a radius of 28.0 cm. The disk is initially spinning at an angular speed of 3.00 rad/s in the CW sense. At t=0.00s a force of 20.0 N is applied to its rim (see figure) to cause a CCW torque. After 15.0 s the disk is observed to be spinning at 4.00 rad/s CCW. What is the Moment of Inertia (kg-m) of the disk? 20 N 3 rad/s 28 cm Rotating Disk
