Solve the below:
Q: Suppose a bullet is fired on a distant planet so that its height (in feet) after t seconds is given by h=-4t2 + 16t +5. The 2 in 4t2 is a small 2, but I don't know how to do that with my keyboard.
a. When is the bullet at its highest point?
b. When will the bullet strike the ground?
c. What is the maximum height the bullet will attain?
Show the whole equation breakdown for these three questions.
