vicinity of thunderstorms. The height of the rocket can be represented by the

following equation:

height = 2.13t^(2) - 0.0013t^(4) + 0.000034t^(4.751)

Create a function called height that accepts time as an input and returns the height

of the rocket. Use the function in your solutions for the following two problems:

1. Compute and plot the time and height of the rocket from the time it launches

until it hits the ground, in increments of 2 seconds. If the rocket has not hit the

ground within 100 seconds, plot values only up through 100 seconds.

Hints: Create a vector for time to use as input to function. Use findfunction on

output to plot positive heights vs. time for flight.

2. Now find and print the time at which the rocket begins to fall back to the ground

and the time at which it hits the ground (when the elevation becomes negative).

Hints: Find each separately. Use a while loop with a condition based on the value

you are looking for. Create your own iterator variable to give you the index to print

when the loop exits.

For 60 sec we can expect 60/50 s to process 1 request

=>for 40 s we have 60/50 * 40 s busy time

=> 60 - 60*40/50 idle time

=>60-48 = 12s
