If you slide down a rope, it’s possible to create enough thermalenergy to burn your hands or your legs where they grip the rope.Suppose a 40 kg child slides down a rope at a playground,descending 2.0 m at a constant speed. How much thermal energy iscreated as she slides down the rope?
Answer:
m = 40 kg
h=2m
Thermal energy created = loss in potential energy = m*g*h = 40*9.8*2 = 784 J
Answer: 784 J
