Answer:

U= 23.544 KJ

Step-by-step explanation:

Given that

mass ,m = 120 kg

Height above the datum ,h = 20 m

Take g = 9.81 m/s²

The potential energy U is given as

U= m g h

m=mass

h=Height above the datum

g=Gravitational constant

Now by putting the value in the above values we get

U= 120 x 9.81 x 20 J

U=23544 J

Potential energy in KJ

U= 23.544 KJ

Therefore the answer will be 23.544 KJ.
