Question

A gymnast is attempting to perform splits. From the information given in the figure below, calculate the magnitude (in N) and direction (in degrees above the horizontal, toward the gymnast) of the force exerted on each foot by the floor.
Her Weight= 520N
The length of her legs is 1.8m and the legnth of 1 leg is .9m her height is .44m please help I would insert the diagram but I dont know how to on this site.

scott · Answer

her legs are of equal length ... so the vertical force components at each foot must be ... 520N / 2 the total force is ... F / .9 = (520 / 2) / .44
