6. The angular position of an object is given by 0 = 8t +7t-20, where O is in radians and tis in seconds. What is: (a) (7 points) The angular velocity at t=2 s? (b) (7 points) The angular acceleration at t=2 s? 7. A 30-kg wheel is rotating and has a radius of 1.5 m. A point on the wheel moving with a constant angular velocity of 300 rev/min. (1 = mr?). (a) (9 points) Determine the linear acceleration of the point. (b) (9 points) At this given angular velocity, what is the rotational kinetic energy?
