Is it possible for the acrobat to rebound to a height greater than her initial height? explain. (select all that apply.) yes. the acrobat can provide mechanical energy by pushing herself up while in contact with the springboard. no. there is no external source of energy to provide the potential energy at a greater height. yes. the acrobat can bend her knees while falling and then straighten them as if jumping when bouncing upward again. yes. elastic energy is always present in the spring and can give the acrobat greater height than initially. no. the kinetic energy that the acrobat gains on the way down is converted entirely back into potential energy when she reaches the initial height.
