3. This time we have a crate of mass 23.7 kg on an inclined
surface, with a coefficient of kinetic friction 0.276. 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 4.34 m/s^2?
40.7 degrees
28.5 degrees
61.1 degrees
34.6 degrees
