Newton's Laws of Motion
Newton's First Law: Inertia
"Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it."
Newton's Second Law: Proportional Values
"The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector."
Newton's Third Law: Opposite Reactions
"For every action there is an equal and opposite reaction."

The three laws of motion can be applied during the long jump in various ways.
Inertia
One of the main examples that inertia comes into play in long jump is friction. The long jumper continues to move in the air until he hits the sand that is at rest and applies an balanced force that causes the long jumper to stop. The sand as well gets displaces.
Proportional Values
If Mike Powell was 87kg and he applied the same amount of force then he does at 77kg he would not be able to jump as he did. Let's examine the equation F=ma. At 77kg Mike Powell's distance if Powell used 450N to jump; 450N=(77kg)(a)| a = 5.84m/s² and @ 83kg --> 450N = (83kg)(a) | 5.42m/s². Therefore as you can see the acceleration when he is 77kg is more therefore translating into a father distance then when he is 83 kg.
Opposite Reactions
This is the easiest applicable of all the three. When the athlete is running he is applying force to the ground and the ground is pushing back against his foot thus creating velocity and thus acceleration and furthermore displacement.

Forces in Long Jump
Force can be calculated by F=ma.
Thus his force exerted would be | F = (77kg)(2.31m/s²) | F= 178 N
---------------------------------------------------------------------------------------
The optimum energy Mike Powell would have while on the ground Ek=(1/2)mv^2 | 6230 J --> Mike Powell uses an enormous amount of energy while he is at his top speed on the ground.
