The questions read... 1.) An Olympic runner leaps over a hurdle. If the runner's initial vertical speed is 2.2 m/s, how much will the runner's center of mass be raised during the jump? 2.) A pendulum bob is released from some initial height such that the speed of the bob at the bottom of the swing is 1.9 m/s. What is the initial height of the bob? What are the formulas I would use? I only want the formulas for now becuase I would like to try and solve it myself. Thanks!!!
