Two children seat themselves on a seesaw. The one on the left has a weight of 360 N while the one on the right weighs 480 N. The fulcrum is at the midpoint of the seesaw. If the child on the right is not at the end however is 1.25 m from the fulcrum and the seesaw is balanced, what is the torque provided with the weight of the child on the left A 100 N uniform ladder 8.0m long rest against a smooth vertical wall. The coefficient of static friction among ladder and floor is .40. What minimum angle can the ladder make by the floor before it slips?
