Answer 1

The potential energy at the top of the second hill is the potential energy at the top of the first hill minus the potential energy lost from friction:

416,500 J – 67,200 J = 349,300 J

The potential energy at the top of the second hill is 349,300 joules.

This answer came straight from the website of Edmentum.

Answer 2

416,500 J – 67,200 J = 349,300 J
