We will apply the concepts related to Newton's second law. At the same time we will convert everything to the system of international units.
The values of the velocities are,
We know that the acceleration is equivalent to the change of the speed in a certain time therefore
Now applying the Newton's second law we have,
Therefore the approximate magnitude is 8516.36N
It is either the mass or density, I believe it is 3 density tho but it could be mass good luck:)
Friction , as the angle gets huger and higher , this is less and less normal force into the inclined plane .
