In the first figure here, a sled is held on an inclined plane by a cord pulling directly up the plane. The sled is to be on the verge of moving up the plane. In the second figure, the magnitude F required of the cord's force on the sled is plotted versus the coefficient of static friction us between sled and plane: F, = 2.1 N, F2 = 4.5 N, and u2 = 0.534. At what angle e (in °) is the plane inclined? TO F F F Number Unit
