Hey guys! This question seems easy, but there's a very interesting trick to solving it. I'll show you the solution in a simple way! (ENEM 2017) The bouncy toy (trampoline) is made up of a horizontal, flexible circular canvas attached to its edge by springs. Children play by jumping on it, changing and alternating their forms of energy. When jumping vertically, disregarding friction with the air and the rotational movements of the body while jumping, a child performs a periodic vertical movement around the canvas' equilibrium position (h = 0), passing through the points of maximum and minimum heights, hmax and hmin, respectively. Schematically, the outline of the graph of the child's kinetic energy as a function of their vertical position in the situation described is: If you need to learn how to solve the biggest doubt in electricity, watch this video [HOW TO KNOW] Resistors in Series or Parallel! • [HOW TO KNOW] Resistors in Series or Parallel...
