The formula h = vt - 512 gives the height (h) of an object, t seconds after being thrown. An object is launched from the ground at a velocity (v) of 40 meters per second.
After how many seconds, I will the object be 75 meters above the ground?
A. t = 1,1 = 3
B. t= 1,1 = 15
C. t = 3,1 = 5
D. 1 = 5,1 = 15
