Answer:
- Corey's max speed is
- the distance Corey's covers in z seconds is
Explanation:
<h3>Corey's max speed</h3>
For constant speed, we know:
The distance between the 80 meters and the 45 meters is:
and the time it took to reach the 80 meter will be:
So, Corey's max speed is
<h3>
How far runs Corey</h3>
As the velocity of Corey's is 
, the distance Corey's covers in z seconds is
<h3>What is Corey's distance from the starting line</h3>
At time 7 + z seconds the distance will be the 45 meters he covers in the first part of the race plus the distance he traveled at constant speed. this is:
At time x ( x greater or equal to 7 seconds) the distance will be the 45 meters he covers in the first part of the race plus the distance he traveled at constant speed. this is:
Answer:
t = 123.59s
Explanation:
For the launch pad section:
Vf = Vo + a*t where Vo=0.
Vf = 35*25 = 875m/s
The distance traveled during the launch:
Now the projectile motion, we know that its initial speed is the speed calculated previously and the initial height is the y-component of the previously calculated distance.
where d= 10937.5m; Vo=875m/s.
Solving for t:
t1 = -11.093s t2 = 98.59s
So, the total time of flight will be:
Answer:
Try and depend more on renewable energy sources. Use products that are more energy efficient. Make use of lighting control measures. Maintain climate change
