  • Gravitational Potential Energy

    A 67 kg bike racer climbs a 1250 m-long section of road that has a slope of 4.3  By how much does his gravitational potential energy change during this climb? Since the biker starts on level ground, initial PE=0J The angle(θ) and hypotenuse length(h) given, we can calculate height. ΔU=mgh First is to find the height. The angle is given…
