In an open space on the school ground drive a 130 cm stick into the ground and let the children stay a record of the length of the shadow, calculated two or three times a day at different seasons of the year.
Total height of the gymnast just before falling back down is=(2+.3)=2.3m Energy gained at that point = m*g*h(m=mass, g=gravitational force, h=height) =55*9.8*2.3=1239.7 J
