We have a crate of mass 43.1 kg on an inclined surface, with a
coefficient of kinetic friction 0.207. Instead of pushing on the
crate, you let it slide down due to gravity. What must the angle of
the incline be, in order for the crate to slide with an
acceleration of 4.59 m/s^2?
1.) 23.4 degrees
2.) 39.0 degrees
3.) 31.2 degrees
4.) 46.8 degrees
