A 70.0-cm diameter flywheel is initially rotating clockwise at 100 rpm. It then undergoes a constant counterclockwise angular acceleration of 2.50 radians per square second for 5.00 seconds.

a) What is the magnitude of the initial angular velocity in units of radians per second?  

b) What are the magnitude and direction of the final angular velocity of the flywheel at the end of the 5.00 second interval in units of rad/s?   

c) What is the magnitude of the net angle that the flywheel turns through during the 5.00 second interval in units of radians?   

d) What is the magnitude of the tangential acceleration of a point on the outer rim of the flywheel during the 5.00 second interval, in units of meters per square second?   

e) What is the initial magnitude of the centripetal acceleration of a point on the rim of the flywheel in units of meters per square second?
