Answer:

Explanation:

The potential energy (U) of an object in a gravitational field is given by the formula:

�

=

�

�

ℎ

U=mgh

Where:

�

U is the potential energy,

�

m is the mass of the object,

�

g is the acceleration due to gravity, and

ℎ

h is the height or distance above a reference point.

In this case,

�

=

120

kg

m=120kg,

�

=

10

m/s

2

g=10m/s

2

, and

ℎ

=

100

m

h=100m.

Substitute these values into the formula:

�

=

(

120

kg

)

(

10

m/s

(

100

m

)

U=(120kg)×(10m/s

2

)×(100m)

�

=

120

,

000

Joules

U=120,000Joules

So, the potential energy of the body falling from 100m is

120

,

000

Joules

120,000Joules.
