Fossil fuels like coal for instance , when they are provided with heat energy (heating them) they start producing Kinetic energy . This kinetic energy will be passed along a turbine which transforms this K.E to an electrical energy used in different useful forms.
Given that the value of the speed of the racing pigeon, the distance it will travel in an hour is 54000 meters.
<h3>What is Speed?</h3>
Speed is simply referred to as distance traveled per unit time.
Mathematically, Speed = Distance ÷ time.
Hence,
Distance = Speed × time
Given that;
- Time elapsed = 1hr = 3600s
Distance = Speed × time
Distance = 15m/s × 3600s
Distance = 54000m
Given that the value of the speed of the racing pigeon, the distance it will travel in an hour is 54000 meters.

Answer:![1.53g](https://tex.z-dn.net/?f=1.53g)
Explanation:
average deceleration= ?
inial velocity: ![u=0](https://tex.z-dn.net/?f=u%3D0)
final velocity: ![v=30m/s](https://tex.z-dn.net/?f=v%3D30m%2Fs)
time: ![t=2seconds](https://tex.z-dn.net/?f=t%3D2seconds)
The first law of kinematics :
![v=u+at](https://tex.z-dn.net/?f=v%3Du%2Bat)
find a the subject of the formula
![a=v-u/ t](https://tex.z-dn.net/?f=a%3Dv-u%2F%20t)
![a=\frac{0-30} 2](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B0-30%7D%202)
![a=-30/2](https://tex.z-dn.net/?f=a%3D-30%2F2)
![a=-15m/s^{2}](https://tex.z-dn.net/?f=a%3D-15m%2Fs%5E%7B2%7D)
The deceleration about g(acceleration due to gravity) will be:
![15/9.8](https://tex.z-dn.net/?f=15%2F9.8)
