The questions read...(adsbygoogle = window.adsbygoogle || []).push({});

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!!!
