Problem: A ball is thrown vertically upward into the air. If the ball started from a height of 101 feet off the ground, use the following formula to represent the projection of the ball
where is the height of the ball after seconds have passed. Based on this information, answer the following questions.
1) When does the ball reach its maximum height?
Your answer must be expressed as a decimal rounded to 2 decimal places with correct units. Hint: The maximum occurs at the vertex of the parabola.
2) What is the maximum height of the ball?
Your answer must be expressed as a decimal rounded to 2 decimal places with correct units.
3) When does the ball return to the ground?
You must use the quadratic formula to solve this problem. Your answer must be expressed as a decimal rounded to 2 decimal places with correct units.
Hint: The ball reaches the ground when the height equals zero.
You can put this solution on YOUR website! I wrote out an explanation of problems 1-2, and took a screen shot. You should be able to see that here. If not, send me an email and I’ll forward it to you.
