The potential energy at the top will be converted into kinetic energy at the bottom. Potential energy-stored energy that has the potential to be converted into other forms of energy. S = [ M] [ LT - 2] [ L] + [ M] [ LT - 1] 2 = [ M 1 L 2 T - 2] + [ M 1 L 2 T - 2] = [ M 1 L 2 T - 2] The .. One end of the rope is attached to the cylinder. The equation for the x-component of force (where x is along the plane of the incline), F=mg (cos - )=ma. w=2piR/T.2. asked Jul 26, 2019 in Physics by IdayaBasu (89. Then I plugged in the masses and solved for the acceleration which should be the same for both boxes and I got 2. mgh= 1/2mv^2 + 1/2Iw^2 . Step 5. 인스타 스토리 필터 and. That gives me a KE of 3/5mgh, so the new (final) height will be 3/5 the original height. H.25/. If the cylinder rolls without slipping, energy must be conserved. The kinetic energy at the bottom consists of two parts: 1/2mv^2 from translation (moving down the slope) and 1/2Iw^2 from rotation. Walter Lewin's video about different shapes falling, which takes
