I am pretty sure I have a and b. I am not sure how to get the time it would be at maximum height and what the maximum height is.

The path of a falling object is given by the function s = -16t^2 + v0t + s0, where represents the initial velocity in ft/sec and represents the initial height in feet.

a) If a rock is thrown upward with an initial velocity of 64 feet per second from the top of a 25-foot building, write the height (s) equation using this information.

Typing hint: Type t-squared as t^2

b) How high is the rock after 1 second?

c) After how many seconds will the graph reach maximum height?

d) What is the maximum height?
