The potential energy of a 40 kg cannon ball is 14000 j. how high was the cannon ball to have this much potential energy?

From the information given, cannon ball weighs 40 kg and has a potential energy of 14000 J.

 We need to find its height.

We will use the formula P.E = mgh

Therefore h = P.E / mg

where P.E is the potential energy,

 m is mass in kg,  

g is acceleration due to gravity (9.8 m/s²)

 h is the height of the object's displacement in meters.

h = P.E. / mg

h = 14000 / 40 × 9.8

h = 14000 / 392

h = 35.7

Therefore the canon ball was 35.7 meters  high.
