A captive James Bond is strapped to a table beneath a huge pendulum made of a 3.0-meter-diameter uniform circular metal blade rigidly attached, at its top edge, to an 8.5-meter-long, massless rod. The pendulum is set swinging with a 10-degree amplitude when its lower edge is 3.4 meters above the prisoner; then, the table slowly starts ascending at 1.0 millimeters/second.

Part A

What is theperiod of the deadly blade pendulum? Express your answer to three significant figures with the appropriate units.

T = ? seconds

Part B

How many oscillations will the deadly blade pendulum make before it reaches James Bond (provided he doesn't stage a dramatic escape first)? Express your answer tothree significant figureswith the appropriate units.

N = ? oscillations
