Answer:

90J

Step-by-step explanation:

Given parameters:

Weight of package = 75N

Height = 1.2m

Unknown:

Potential energy = ?

Solution:

Potential energy is energy due to the position of a body. It is mathematically expressed as;

Potential energy = mgh

m is the mass

g is the acceleration due gravity

h is the height

The weight is mg

Potential energy = 75 x 1.2 = 90J
