The potential energy of a 40kg cannon ball is 14000j. how high was the cannon ball

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 .

Most British Commonwealth nations changed from the imperial system of units to the metric system. Several of these nations rapidly and successfully made the metric transition, thanks to strong government encouragement and support. In addition, other countries have also made the change.
