Na figura abaixo despreze as forças dissipativas e calcule o valor da carga Q, sabendo que o rapaz exerce uma força de 15N para mantê-la em equilíbrio. ME AJUDE POR FAVOR!!!

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

explanation:
