Question

a

Answer 1

1) The trapeze artist at the left side, uses the centrifugal force, in order to join the trapeze artist at the right side of the picture.

2) The trapeze artist at the right side of the picture, uses the force exerted by his hands against the weight force, which is acting on the trapeze artist at the left side, once the same trapeze artist at the left side of the picture has joined the trapeze artist at the right side of the picture

3) Due to the force, which both trapeze artists exert by their hands, they can oscillate above the earth surface, furthermore, those oscillations are possible thanks to the force exerted by the knees of the trapeze artist at the right side of the picture

Answer 2

thanks! :)
