A 14.0 ft long see-saw has its fulcrum in the middle and has four kids sitting on it. A 680 lb kid sits on the left end and a 76.0 lb kid sits 2 50 ft in front of him A 94.0 lb kid sits on the right end and another kid sits 2 50 ft in front of him. How much must this kid weigh to balance the see-saw?

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 790 n/m. it is initially at rest on an inclined plane that is at an angle of 28 degrees with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is k = 0.14. in the initial position, where the spring is compressed by a distance of a = 0.18 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
