Question

equation : h(t) = -16t2 + 32t + 3
answer the following questions.
How high off the ground will the ball be after 2 seconds? Show your work
Why is the height the same at .5 seconds and 1.5 seconds and what is the height?
a) How long is the ball in flight? Round answer to nearest hundredth.

b) Which formula, process, etc. did you use to solve this problem?

Answer 1

replace \(t\) by \(2\) to get your first answer

Answer 2

second answer is because what goes up must come down, so it is rising at .5 seconds and falling at 1.5 seconds

Answer 3

for "how long" set \(h(t)=0\) and solve for \(t\)

Answer 4

i still have no clue on what to do, i suck at algebra
