Answer:
a) t = 2 seconds
b) 6.05 meters
Step-by-step explanation:
I prefer a graph for questions like this, but I have attached a table, too. Here, the table is created using a graphing calculator to evaluate the function. A spreadsheet can do this nicely, too.
The maximum height occurs at t=0.9 seconds, and the ball hits the ground at a time that is slightly more than double that, 2.0 seconds.
The maximum height is 6.05 meters.
