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
If an object is moving, then its speed and the magnitude
of its velocity aren't zero.
If its velocity is constant (speed doesn't change and it's
moving in a straight line), then its acceleration is zero.
Looks like choice-D sums it up nicely.
It transforms it to mechanical
The Coriolis effect is strongest at the north and south poles, and zero on the equator (zero latitude).
