5.4.1
With all of his gear on, Batman has a mass of 90.7 kg. How much potential energy does he have if he's perched on top of a 1,575 m building?
142,852.5 J
1,399,954.5 J
0.058 J
17.36 J
Answer explanation
This question links to success criteria 5.4.1: I can calculate both gravitational potential energy and kinetic energy for an object.
If you got it correct place a check mark in the question results section. If you got it incorrect place an X in that section. If this was a redemption question, cross out the one X and replace it with a check mark.
