Hints:
The Earth's energy does not come from eating a balanced diet,
or from ninja turtles, or from getting sleep and exercise.
There are no hamsters running on a treadmill inside the Earth.
God didn't wind up a big spring to operate the Earth.
The Sun provides, and has always provided, almost all of the energy
used on Earth. It was the energy that got stored in dead dinosaurs
to make gas and oil, and it's the energy that makes plants grow, and
gets stored in them so we can get the energy by eating the plants.

(a)The required speed for take off will be 24.49 m/sec.
(b)The minimum length must the runway have 193 m.
<h3>What is speed?
</h3>
Speed is defined as the rate of change of the distance or the height attained. it is a time-based quantity. it is denoted by u for the initial speed while v for the final speed. its SI unit is m/sec.
(a)The required speed for take off will be 24.49 m/sec.
From the Newtons third equation of motion;
Hence, the required speed for take off will be 24.49 m/sec.
(b)The minimum length must the runway have 193 m.
From the Newtons third equation of motion;
Hence, the minimum length must the runway have 193 m.
