his time we have a crate of mass 31.8 kg on an inclined surface, with a coefficient of kinetic friction 0.243. 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 7.62 m/s^2? 47.1 degrees 62.7 degrees 31.4 degrees 81.5 degrees
