The full question is attached in the first picture.

The answer is attached in the second picture

Max height = 5 feet at time = 5s

Time to ground = 10s

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

suppose h(t)=-0.2t^2+2t models the height, in feet, of a ball that is kicked into-example-1

suppose h(t)=-0.2t^2+2t models the height, in feet, of a ball that is kicked into-example-2
