The two highest points of the ball’s trajec-
tory are Q and Q?; at these points the string is
±24o from the vertical. Point P is the lowest
point of the ball’s trajectory where the string
hangs vertically down.
The acceleration of gravity is 9.8 m/s2.

A) What is the magnitude of the ball’s accelera-
tion at the point Q?
Answer in units of m/s2.
