Acrate is resting on a ramp that is inclined at an angleabove
the horizontal. as the angle is incrased the crateremains in place
until the angle reaches a value of 38degrees. then the crate begins
to slide down the slope. (a) determine the coefficient of static
friction between the crateand the ramp surface. (b) the coefficient
of kinetic frictionbetween the crate and the ramps surface is
0.600. find theacceleration of the moving crate.
