Question

Calculate the potential energy of a 40 gram sparrow resting on a branch 30 feet above the ground

Answer 1

PE = mgh

PE = (0.04) (9.8) (9.144)
= (0.392) (9.144)
= 3.584448 J

Approximately = 3.6 Joules

Answer 2

1.43 J

Step-by-step explanation:

PE = mgh = (0.04 kg)(9.80 m/s2)(3.6576 m) = 1.43 J

You have to convert g to kg, and feet to m
