Halliday, Resnick & Walker — Equilibrium and Elasticity: Problem 1
1 A thief intends to enter an apartment by climbing a ladder but foolishly places the upper end against a window. When he is 3.00 m up the ladder, the window is on the verge of shattering. His mass is 90.0 kg, the ladder’s mass is 20.0 kg, the ladder’s length is 5.00 m, and the foot of the ladder is 2.50 m from the base of the wall, on a non-slip ground surface. What are (a) the magnitude of the force on the glass from the ladder, (b) the magnitude of the force on the ladder from the ground, and (c) the angle between that ground force and the horizontal?
