Question 95079: If a ball is thrown upward from the roof of a building 80 m tall with an initial velocity of 15 m/s, its approximate height h after t is given by
h = -5t^2 + 15t + 80.
When we used feet, the t^2-coefficient was -16 (from the fact that the acceleration due to gravity is approximately 32 ft/s^2). When we use meters as the height, the t^2-coefficient is -5 (that same accelerations becomes approximately 10 m/s^2). Use this information to solve 31 and 32.
31)Science and Medicine: When will the ball reach a height of 85 m?
32)Science and Medicine: How long does it take the ball to fall back to the ground?

Question 102209: Building on question 95079, I have the part that goes like this:The only part of the height equation that we have not discussed is the constant. You have
probably noticed that the constant is always equal to the initial height of the ball (80 m in
our previous exercises). Now, let’s have you develop a height equation.
A ball is thrown upward from the roof of a building 100 m tall with an initial velocity
of 20 m/s. Use this information for exercises 35 to 38.
35. Science and medicine. Write the equation for the height of the ball.
36. Science and medicine. When will the ball reach a height of 80 m?
I am trying to solve #36. So far I have:
h=-5t^2+20t+100
0=t^2-4-20
0= 4+or-sqrt-5^2-4*1*-20/2*1
=4+or-sqrt16+80/2
4=+or-sqrt96/2
4+9.8/2=13.8/2=6.9
4-9.8/2=5.8/2=2.9
am I anywhere near where I need to be?
Thank you so much.
