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
5000 feet = 0.947 miles.
Speed= ?
Distance=o.947 miles
Time= 0.1 hours
Speed=distance/time
= 0.947/0.1
=9.47 miles per hour
