A uniform 30kg ladder length 750m leans against a smooth

Reference no: EM13622229

A uniform 30kg ladder (length =7.50m) leans against a smooth vertical wall. The base of the ladder is 12 ft from the wall. If the coefficient of friction between the ground and the ladder is 0.20, how far up the ladder can a 120kg fire fighter climb before the ladder begins to slip.
