Answer:
a. Job A 1. 6 2.12 3.18 4.24 5.30 6.36 Job B 1. 10 2. 14 3.18 4.22 5.26 6.30
b. she will make the same amount of money at 3 hours.
c. Priya should take the first job ( Job A), because even with the 6 dollar bonus for the first hour, the second job (Job B) would be paying less money after 3 hours.

Step-by-step explanation:
<span>In general, the height of a projectile is given by
</span>
![h= -\frac 1 2 g t^2 + v t + h_0](https://tex.z-dn.net/?f=h%3D%20-%5Cfrac%201%202%20g%20t%5E2%20%2B%20v%20t%20%2B%20h_0)
<span>
where </span>
![h](https://tex.z-dn.net/?f=h)
is the height at time
![t](https://tex.z-dn.net/?f=t)
of a projectile shot upward at velocity
![v](https://tex.z-dn.net/?f=v)
from initial height
![h_0](https://tex.z-dn.net/?f=h_0)
<span>.
The acceleration of gravity </span>
![g= 9.8 \textrm {m/s}^2 \textrm{ or } g=32\textrm{ feet/s}^2.](https://tex.z-dn.net/?f=g%3D%209.8%20%5Ctextrm%20%7Bm%2Fs%7D%5E2%20%5Ctextrm%7B%20or%20%7D%20g%3D32%5Ctextrm%7B%20feet%2Fs%7D%5E2.)
<span> We give it a negative sign in the equation because it pulls down.
Let's apply it to each group.
Group A launches a tennis ball straight up with an initial velocity of 19 meters per second.
We have MKS units, positive (upward) velocity and an initial height of 0.
</span>
![h= -\frac 1 2(9.8) t^2 + (19) t + 0 = -4.9t^2 + 19t](https://tex.z-dn.net/?f=h%3D%20-%5Cfrac%201%202%289.8%29%20t%5E2%20%2B%20%2819%29%20t%20%2B%200%20%3D%20-4.9t%5E2%20%2B%2019t)
<span>
Group B launches a tennis ball straight up with an initial velocity of 50 feet per second. Not metric, velocity +50, initial height zero.
</span>
![h= -16t^2 + 50t](https://tex.z-dn.net/?f=h%3D%20-16t%5E2%20%2B%2050t)
<span>
Group C drops a tennis ball from a height of 19 meters.
MKS, initial height 19, initial velocity zero.
</span>
![h= -\frac 1 2 g t^2 + v t + h_0 = -4.9 t^2 + 19](https://tex.z-dn.net/?f=h%3D%20-%5Cfrac%201%202%20g%20t%5E2%20%2B%20v%20t%20%2B%20h_0%20%3D%20-4.9%20t%5E2%20%2B%2019)
<span>
Group D drops a tennis ball from a height of 50 feet.
</span>
![h= -16 t^2 + 50](https://tex.z-dn.net/?f=h%3D%20-16%20t%5E2%20%2B%2050)
