Answer:

90J

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
