A bob of mass of 0.18 kilograms is released from a height of 45 meters above the ground level. What is the value of the kinetic energy gained by the bob at the ground level?

Looks as though Jim and the bob have a similar "problem" ... ke = one half of mass times velocity squared. Velocity comes from the KINEMATIC EQUATIONS (as ever), with acceleration = about 10. http://perendis.webs.com
