Anna_03 - 20.01.2016 00:12A 72kg skateboarder on a 1.5kg skateboard is on top of a ramp with a vertical height of 4.0 m what is the skateboarders maximum potential energy at the bottom of the ramp?

Patrick Simpson - 20.01.2016 00:48The formula for a kinetic potential P of a falling body is P = mgh where m = mass, g = acceleration due to gravity (9.8 m/s^2, constant), h = height. The total mass of a skateboader and a skateboard is 72 + 1.5 = 73.5 kg. P = 73.5*9.8*4.0 = 2881.2 J
