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 the figure below, where the readings are 0.25 s apart and the ball is released at t = 0. On the horizontal axis, x1 = 20 ft.(adsbygoogle = window.adsbygoogle || []).push({});

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

ft/s

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

ft/s

(c) What is that maximum height?

ft

i tried to find part c first. since i know that time is equal to 1.25 seconds i used deltay=.5at^2

.5(32)(1.25)^2

25 feet

this did not work so I do not know what to do?

any one with any help. thaks
