3. This time we have a crate of mass 32.0 kg on an inclined surface, with a coefficient of kinetic friction 0.225. 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 3.43 m/s^2?     22.8 degrees     32.6 degrees     13.0 degrees     42.4 degrees
