The answer is attached in the second picture
Max height = 5 feet at time = 5s
Time to ground = 10s
Step-by-step explanation:
If we have such an explicit representation of the path of the ball, we can easily plot the graph with a calculator or a graphing tool, and find its behaviour.
The maximum height (peak of the graph) occurs at t = 5s and has a value of 5 feet.
We can also verify from the graph that the ball touches the ground in 10 s
