Michelle throws a frisbee into the air. The height of the frisbee at a given time can be modeled by the equation h(t)= -2t

(a) The ball will hit the ground after 3 seconds

(b) The maximum height is 6.125

Step-by-step explanation:

Given

Solving (a): When the frisbee will hit the ground?

To do this, we set h(t) to 0

So, we have:

Expand

Factorize

Factor out t - 3

Split:

Solve for t in both equations

Time can't be negative; So:

Solving (b): How height the frisbee will go?

First, we calculate time to reach the maximum height

Where:

By comparison:

So:

So, the maximum height is:

2 x t divided by n
