Explanation:
A car travels 6.0 km to the north and then 8.0 km to the east. The intensity of the position vector, in relation to the starting point is: a) 14 km b) 2.0 km c) 12 km d) 10 km e) 8.0 km

The intensity of the position vector is equal to the displacement,
So, to calculate the displacement, we need to find the length of the straight line from starting point to end point.
So, applying Pythagorean theorem
c² = a² + b²
R² = 6² + 36²
R² = 36 + 64
R² = 100
R = √100
R = 10 km.

La intensidad del vector de posición es igual al desplazamiento,
Entonces, para calcular el desplazamiento, necesitamos encontrar la longitud de la línea recta desde el punto inicial hasta el punto final.
Entonces, aplicando el teorema de Pitágoras
c² = a² + b²
R² = 6² + 36²
R² = 36 + 64
R² = 100
R = √100
R = 10 km.
To solve this exercise it is necessary to take into account the concepts related to Pressure depending on the Force and the Area.
The pressure is defined as
Where,
Our values are given as,
Where is the mass of the person and
is mass of cycle. Therefore the total mass at the system is 105Kg.
For Newton's second law we have:
where a is the acceleration, in this case the same Gravitational acceleration.
We need to make two considerations, the first is to calculate the total weight and second to calculate the weight on each wheel (2), that is
Force in each wheel,
In this way we can now calculate the length based on the pressure, that is
Therefore each tire has 3.21cm
