The Coordinate Methodology is a technique for <em>converting geometrical images into formulas</em>, a technique for describing visuals with letters and numbers representing constant and factors. It is essential in learning calculus and other mathematical topics, and the further calculation can be defined as follows:

Answer:
The horizontal component of the truck's velocity is: 23.70 m/s
The vertical component of the truck's velocity is: 3.13 m/s
Explanation:
You have to apply trigonometric identities for a right triangle (because the ramp can be seen as a right triangle where the speed is the hypotenuse), in order to obtain the components of the velocity vector.
The identities are:
Cosα=
Senα=
Where H is the hypotenuse, α is the angle, CA is the adjacent cathetus and CO is the opposite cathetus
The horizontal component of the truck's velocity is:
Let Vx represent it.
In this case, CA=Vx, H=24 and α=7.5 degrees
Vx=(24)Cos(7.5)
Vx=23.79 m/s
The vertical component of the truck's velocity is:
Let Vy represent it.
In this case, CO=Vy, H=24 and α=7.5 degrees
Vy=(24)Sen(7.5)
Vy=3.13 m/s
The gravitational force of attraction between two objects is directly proportional to the product of the two masses and inversely proportional to the square of the distance between them.
Where,
G = Gravitational Universal Constant
M = Mass of the Planet
m = Mass of the object
r = Distance
Therefore the amount of force exerted by the first object on the second object is equal to the amount of the force exerted on the second object by the first.
The gravitational force exerted by Larry on the Earth is same as the force exerted on Larry by the Earth.
That is 300N.
