If a ball is dropped from the top of a 256-ft building, then the formula
h(t)= 256-16t^2expresses its height h(t) in feet as a function of the time t in seconds.
a. Find h(2), the height of the ball 2 seconds after it is dropped.
h(t)= 256-16t^2
sub 2 for t
h(2) = 256 - 16*2^2
-----
b. Find h(4)
sub 4 for t
