Answer
672,000 Joules
Explanation
Gravitational potential energy (P.E) is the energy possessed by a body that is at a potential height from the ground.
IT is calculated by the formula;
P.E = mgh
Where m ⇒ mass
g ⇒ acceleration due to gravity
h ⇒ height from trhe ground.
P.E = 1200 × 1.6 × 350
= 672,000 Joules.
