- A wooden plank is supported at two points as shown. What is the shortest distance from the end that a 80-kg person can stand without the other end lifting up? The plank is uniform, and its mass is 20.0 kg.A child with a mass of 24.3 kg sits on a see-saw, 2.75 m from its center (on its fulcrum). How far from the fulcrum should the child’s 56.4 kg mother sit to balance the child? Equations: Fg = mg t = Fr^ tccw = tcwEmma and Noah are playing on a seesaw. Noah, mass 22 kg, is seated 1.6 m away from the pivot point. Emma, mass 25 kg, wants to sit at a point that will make the seesaw exactly balance on its pivot. How far away from the pivot must she sit? Assume that the mass of the seesaw itself is small enough to ignore.
- A 4.8 m ladder rests against a wall as shown. The ladder has a mass of 26.4 kg. A 57.6 kg person stands on the ladder at a distance of 3.5 m from the bottom of the ladder. The foot of the ladder is 1.9 m from the bottom of the wall. Assume there is no friction between the ladder and the wall so that the force of the wall on the ladder is acting only in the horizontal direction. However, there is a friction force between the ladder and the ground. (a) What is the force, in N, exerted by the wall on the ladder? (b) What is the normal force, in N, exerted by the floor on the ladder? (c) What is the friction force, in N, between the ladder and the ground?A board has its mass of 30.0 kg uniformly distributed along its' length of 4.00 m.
