A pendulum consists of a sphere of mass 1.3 kg attached to a light cord of length 10.9 m. The sphere is released from rest when the cord makes a 52.3 degree angle with the vertical, and the pivot at P is frictionless. The acceleration of gravity is 9.8 m/s squared.
1) Find the speed of the sphere when it is at the lowest point in m/s----answer 10.27 m/s is wrong so what is the correct answer in the correct number of significant digits
2) What is the tension of the cord at the lowest point in N--answer 2.92 N is wrong--what is the correct answer in the correct number of signficant digits
