You should ask what type of technology he uses to track hurricanes!
You should also ask why is it important to improve hurricane forecasts!
Hope this gives you some ideas :)
<span>Things you should know before answering... At its absolute highest point the velocity of a ball will be 0 m/s.
1. You have Vi,Vf, and a. You're looking for d so the best equation is: vf^2=Vi^2+2ad (0=26.5^2+2(-9.81)d).
0=702.5-19.62d
-702.5=-19.62d
d=35.793 meters
2. You now have Vi,Vf,a, and d. You are looking for t. There are many equations you can use but to keep things simple we will use: Vf=Vi+at (0=26.5-9.81t)
-26.5=-9.81t
t=2.701 seconds
3. You just have to double the time it took to reach the top.
4. Depends on what the question means. Theoretically at the starting point if the ball is no longer travelling it's at 0. If not then you should know that the descent on something falling vertically is mirrored exactly to the ascent meaning that the final speed is 26.5 m/s.
Vf^2=Vi^2+2ad
Vf^2=0+2(-9.81)35.793
vf=sqrt(702.259)
vf=26.5001</span><span>

Answer:
80m, assuming g=10m/s^2
Explanation:
40m/s will be reduced to 0m/s in 4 seconds. 4 seconds x 40m/s would be 160m up, but you will only get half of that because you decelerate linearly to 0m/s. This leaves you with 4 x 20 = 80m.
