Unformatted text preview: the other end, the puck has drifted 2cm to the right, but still has the same velocity along the length. What is the inclination of the table? Problem 8 A ball of mass m is attached to the ceiling by a rope of length L , and swings back and forth as a pendulum. As the rope swings through the vertical, the ball has speed v . What is the tension in the rope at this instant? Problem 9 (Based on a lecture demonstration) A closed chain is in the shape of a circle of radius R and spinning about its center. Every point on the chain has speed v . By examining a small piece of the chain, show that the tension in the chain is T = 1 2 π mv 2 /R where m is the total mass of the chain. 1...
