The potential energy is defined as the energy is contained in the body due to the height over the surface of the earth and it is calculated from the equation
<em>where:</em>
- PE: the potential energy in Joules.
- m: the mass of the body in kg.
- g: the acceleration due to the gravity in m/
- h: the height of the body over the earth in meters.
<em>in our problem:</em>
Answer: example 1: increase force applied to object. Example 2: Increase distance over which work applied. Example 3: Change direction of applied force.
Explanation:
As per Einstein's theory of relativity, the closer the clock is to the source of gravitation, the slower the time passes. Clocks close to massive bodies slow down. The time difference between two events will be very large. Time difference between two clock ticks will take extremely large amount of period.
it is confirmed by tests of general relativity.
Black holes are strongly densed matter. the gravitational attraction influences the clock ticks. Atomic clocks run a little faster on aeroplanes , away from surface of earth. Very close to back hole, where attraction and gravity is extremely high, clock ticks so slow that time can be thought of as stopped...

(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.
