WebSolve the following word problems using the kinetic and potential energy formulas (Be sure to show your work!) Formulas: KE = 0.5 x m x v2 OR PE = m x g x h v = velocity or speed m = mass in kg g = 9.81m/s2 h = height in meters 15. You serve a volleyball with a mass of 2.1 kg. The ball leaves your hand with a speed of 30 m/s. The ball has WebThis is because kinetic and potential energy are both proportional to the mass of the object. In a situation where KE = PE, we know that mgh = (1/2) mv2. Dividing both sides by m and rearranging, we have the relationship 2 gh = v2. Practice Problems 5. A child slides down a playground slide.
