Question

A skydiver is about to jump from an airplane that is 1,500 meters above the ground. The diver has a mass of 125 kg. What is the potential energy at this height? Show your work.

Answer 1

Gravitational Potential energy is the energy stored with regard to position.

the equation for potential energy is as follows

P.E = mass x gravitational acceleration x height from the ground

gravitational acceleration - 9.8 ms⁻²

substituting the values in the equation

P.E = 125 kg x 9.8 ms⁻² x 1500 m

P.E = 1 837 500 J

therefore the potential energy of the diver at 1500 m high is 1 837 kJ

Answer 2

The potential energy of the skydiver from the given height is 1837.5kJ.

Given the data in the question;

• Mass of the diver; $m = 125kg$

• Distance from the ground; $h = 1500m$

Potential energy; $U = \ ?$

Gravitational potential energy

Gravitational potential energy is simply the potential energy an object possesses in relation to another object due to gravity.

It is expressed as:

$U = mgh$

Where m is the mass of the object, h is its height from ground level and g is acceleration due to gravity ( $g = 9.8m/s^2)$

Now, to determine the potential energy of the diver, we substitute our values into the expression above.

$U = mgh\\\\U = 125kg\ *\ 9.8m/s^2\ *\ 1500m\\\\U = 1837500kgm^2/s^2\\\\U = 1837500J\\\\U = 1837.5kJ$

Therefore, the potential energy of the skydiver from the given height is 1837.5kJ.
