Answer:
This is the right answer −4c+11
Step-by-step explanation:
<span>200/40=5 5/2=2.5 2.5+5=7.5 30/7.5 = 4 hours</span>
Remember that c is the initial height. Since we the rocket is in a 99-foot cliff, c=99. Also, we know that the velocity of the rocket is 122 ft/s; therefore v=122
Lets replace the values into the the vertical motion formula to get:

Notice that the rocket hits the ground at the bottom of the cliff, which means that the final height is 99-foot bellow its original position; therefore, our final height will be h=-99
Lets replace this into our equation to get:


Now we can apply the quadratic formula

where a=-16, b=122, and c=198


or


or


or

Since the time can't be negative, we can conclude that the rocket hits the ground after 9 seconds.
(16+5)4÷2=42
21×4÷2=42
84÷2=42
42=42
