An inclined plane is sliding, and accelerating, on a horizontalfrictionless surface. There is a block at rest on the slopingsurface, held in place by a static friction through the horizontalacceleration of the system. the coefficient of static frictionbetween the block and the inclined plane is 0.615. the slope of theincline plane is 42.5 degrees with respect to the horizontal.
a) What is the minumum acceleration of the inclined plane forthe square block not to slide?
I found a=1.891 m/s^2
b) what is the maximum acceleration of the inclined plane forthe square block not to slide?
