The pitcher in a slow-pitch softball game releases the ball at a point 3.0 ft above ground

Question:

The pitcher in a slow-pitch softball game releases the ball at a point 3.0 ft above ground level. A stroboscopic plot of the position of the ball is shown in Figure, where the readings are 0.25 s apart and the ball is released at t = 0.

(a) What is the initial speed of the ball?

(b) What is the speed of the ball at the instant it reaches its maximum height above ground level?
