We will use the formula p = mgh
p is potential energy.
m is mass of object in kg
g is acceleration due to gravity (9.8m/s²)
h is height of the objects displacement in meters.
p = mgh → mgh = p → h = p / mg
p is 14000j, m is 40kg and g is 9.8 m/s²
h = 14000 / 40 × 9.8 → h = 1400 / 392 → h = 35.7
Therefore , the cannonball was 35.7 meters high .
