I had to do it on a separate sheet. Look for the picture I attached.
Because when the explosion is still occurring and is making the universe bigger
Answer:
maintaining internal balance
Explanation:
this question is in biology not physics
Well since there are no options i would guess a cave or a space that is very empty with walls that can reflect sound
<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>
