Question

PLEASE HELP ME!

I NEED ANSWERS NOW! NO FILES!
A group of students makes a toy rocket for a physics class. The function h(t) = -16t2 + 96t + 1 models the flight of a toy rocket, where h(t) is the height of the toy rocket in feet after t seconds.
Part A: What is the maximum height of the toy rocket?

Part B: After how many seconds will the toy rocket reach its maximum height?

Part C: The students make some modifications to the toy rocket and it is launched a second time in hopes of making the rocket fly higher. This time the rocket's flight is given by the equation: h(t) = -16t2 + 80t + 3. Did the rocket fly higher the first or second time? Explain how you know this.

Answer 1

Here is what I answered with, I'm not 100% sure it is correct.

Part A:

The maximum height of the toy rocket would be 145.

Part B:

After 3 seconds the toy will reach its maximum height.

Part C:

The toy rocket flew higher the first time, the maximum height of the rocket the 1st time 145, the second time however the maximum height was only 103.
