Having failed in his first attempt, Romeo acquires a new ladder to try once again to get to Juliet’s window. This one has a length L and a weight of 200 N. He tries placing it on the other side of the window, where the coefficients of static friction are 0.4 between the ladder and the wall, and 0.7 between the ladder and the ground. Because of bruises suffered in his last fall, Romeo wears heavy padding, which gives him a total mass of 80 kg. Sure enough, when he is 4/5 of the way up the ladder, it begins to slip. What was the angle between the ladder and the ground when Romeo was making his ascent?
