Gravitational potential energy on a slope
WebYou'll get a detailed solution from a subject matter expert that helps you learn core concepts. Question: A 72 kg bike racer climbs a 1200-m-long section of a road that has a slope of 4.3 degrees. By how much does his gravitational potential energy change during this climb? A 72 kg bike racer climbs a 1200-m-long section of a road that has a ... WebThe loss of gravitational potential energy from moving downward through a distance h equals the gain in kinetic energy. This can be written in equation form as −ΔPE g = ΔKE. Using the equations for PE g and KE, we can solve for the final speed v, which is the desired quantity. Solution for Part 1
