1) A girl standing on an ice rink is pulled by three force simultaneously: 100N force due east, 200N force due south and 500N force N30?W (30?W of N). Find the resultant force on the girl using the component method.
2) An object of weight 100N is suspended from two ropes 3m and 4m in length attached to two points 5M apart on a horizontal beam. Find the tensions in the two ropes.
3) A light plank (weight is assumed to be negligible) 10.0m long is projecting over the edge of a building with 2.0m of its length protruding. How far out along the protruding part can a person of mass 124kg walk before the beam tilts, if there is an object of mass 18kg on the other end of the plank.?
4) a 45kg child on a swing at its highest point is 2.00m above the ground. Calculate the maximum kinetic energy if the lowest point of the swing is 0.50m above the ground
