4) A crate is at rest on an inclined plane. As the slope increases the crate remains at rest until the incline reaches an angle of 32.70

from the horizontal. At this angle the crate

begins to slide down the ramp.
A) What is the coefficient of static friction between the crate and the surface of the
ramp?
B) If the coefficient of kinetic friction between the surface of the ramp and the crate is
0.33, what would be the acceleration of the moving crate at this angle?

also need this before tomorrow
