Simple pendulum, is show in several states In case A the mass is travelling back down to the bottom and is in between the bottom and its max height. 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? Grade Sun O
It is maximum in case A O
It is maximum in case B O
It cannot be determined O
It is zero in all cases. O
It is maximum in case C
It is equal in all cases, but is non-zero

The correct statement about the magnitude of the angular acceleration is, t is maximum in case C.

The angular acceleration of an object is defined as the change in angular velocity per change in time of motion.

The angular velocity of an object is defined as the change in angular displacement per change in time of motion.

Angular acceleration is related to linear velocity in the following equation;

Angular acceleration will be maximum when linear velocity is maximum.

The linear velocity of the ball is maximum at the lowest position.

Thus, we can conclude that the correct statement about the magnitude of the angular acceleration is, t is maximum in case C.
