Question

Dean Potter is known for slacklinging across a 615 meter deep ravine in Yosemite National Park with no safety gear. If his mass is 67 kg, how much potential energy did he have?

Answer 1

Explanation:

the gravitational potential energy applies.

the formula :

PE = m×g×h

mass × gravitational acceleration × height

in our case

PE = 67 kg × 9.81 m/s² × 615 m = 404,221.05 J
