The force that is pushing the crate up the ramp is competing with at least another two forces, those being G force= defines the attraction to the earth and Ff, the friction between the crate and the rough material of the ramp
Any Force can be defined by the weigh of a particular body and the acceleration
the kinetic friction indicative would be defined by the report between the active force and the friction force, considering G
So 5000-22%×5000=250× a
a=3900/250 m/s
I have no idea what the exact answer is, so sorry in advance but ik it’s definitely less than four, but greater than three.. lol hope that helps some
The third one because it is a small one and it had high and high temp so it has the most modecules.
Hope this helps
