What is the potential energy of a 150 kg diver standing on a diving board that is 10 m high?

U = 14700 J

Explanation:

As we know that gravitational potential energy is given as

here we know that

m = 150 kg

g = 9.8 m/s/s

h = 10 m

now from above equation we know that

so here correct answer will be

d. 15,020 J

0.55x745.7j and a calculator

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
