A body weighing 85 g falls from a height of 200 cm. Determine the potential energy of the body.

Initial data: m (mass of the falling body) = 85 g (85 * 10-3 kg); h (height from which the body began to fall) = 200 cm (2 m).

Reference data: g (acceleration due to gravity) ≈ 10 m / s2.

The potential energy of the body in question at the moment of the beginning of the fall can be determined by the formula: En = m * g * h.

Calculation: Ep = 85 * 10-3 * 10 * 2 = 1.7 J.

Answer: Before the start of the fall, the body in question had a potential energy of 1.7 J.
