A non uniform fire escape ladder is 6.0 m long when extended to the icy alley below. It is held at the top by a frictionless pivot, and there is negligible frictional force from the icy surface at the bottom. The ladder weighs 250 N, and its center of gravity is 2.0 m along the ladder from its bottom. A mother and child of total weight 750 N are on the ladder 1.5 m Crom the pivot. The ladder makes an angle 0 with the horizontal. Find the magnitude and direction of (a) the force exerted by the icy alley on the ladder and (b) the force exerted by the ladder on the pivot. (c) Do your answers in parts (a) and (b) depend on the angle ????

(c) Do your answers in parts (a) and (b) depend on the angle Solution 58P Step 1 : Introduction : Here, we have non uniform fire escape ladder extended to the icy alley below, it is held at the top by the frictionless pivot and negligible frictional force from the icy surface at the bottom We need to find the force exerted by the icy alley on the ladder In the second part we need to find the force exerted by the ladder on the pivot And we need to check if the force obtained depends on the angle
