In case B the mass is at its max height and has a speed of zero. In case C the ball is at its lowest position.Which of the following statements about the magnitude of the mass's angular acceleration is true?a) It is maximum in case A.b) It is maximum in case B.c) It cannot be determined d) It is zero in all cases. e) It is maximum in case C.f) It is equal in all cases, but is non-zero.

In a science museum, a 110kg brass pendulum bob swings at the end of a 13.2m -long wire. The pendulum is started at exactly 8:00 a.m. every morning by pulling it 1.7m to the side and releasing it. Because of its compact shape and smooth surface, the pendulum's damping constant is only 0.010 rm kg/s. At exactly 12:00 noon, how many oscillations will the pendulum have completed? And what is its amplitude?

Rank each pendulum on the basis of the maximum kinetic energy it attains after release. Rank from largest to smallest. To rank items as equivalent, overlap them.
