Question

Humpty Dumpty (5 kg) is about to a bungee jump from a 50-meter high bridge. Feeling nervous, he paces back and forth with a velocity of 2 m/s. What is Humpty Dumpty's GRAVITATIONAL POTENTIAL ENERGY before jumping?

Answer 1

Answer:

E = 2450 J

Explanation:

Given that,

Mass of Humpty Dumpty, m = 5 kg

He jumps from a 50 m high bridge.

Feeling nervous, he paces back and forth with a velocity of 2 m/s.

We need to find Humpty Dumpty's gravitational potential energy before jumping. The formula is given by :

$E=mgh\\\\E=5\times 9.8\times 50\\\\E=2450\ J$

So, the required gravitaional potential energy is 2450 J.
