Answer:
The answer to the question is
3340800 m far
Explanation:
To solve the question, we note that acceleration = 29 m/s²
Time of acceleration = 8 minutes
Then if the shuttle starts from rest, we have
S = u·t+0.5·a·t² where u = 0 m/s = initial velocity
S = distance traveled, m
a = acceleration of the motion, m/s²
t = time of travel 
S = 0.5·a·t² = 0.5×29×(8×60)² = 3340800 m far

Answers:
a) -2.54 m/s
b) -2351.25 J 
Explanation:
This problem can be solved by the <u>Conservation of Momentum principle</u>, which establishes that the initial momentum  must be equal to the final momentum

 is the velocity of the second football player (to the north)
 is the final velocity of both football players
 is the final velocity of both football players
With this in mind, let's begin with the answers:
a) Velocity of the players just after the tackle

The intensity of a sound wave is defined as the amount of energy passing through a unit area of the wave front in unit of time.
        
             
        
        
        
Answer:
Glow
Explanation:
Actually, it is the air in front of the meteoroid that heats up. The particle is traveling at speeds between 20 and 30 kilometers per second. It compresses the air in front, causing the air to get hot. The air is so hot it begins to glow — creating a meteor - the streak of light observed from Earth.
Hope this helped!
