What is the potential energy og a 50 newton object resting on the edge of a cliff of a 30 meter cliff?

The potential energy (PE) of an object can be calculated using the formula PE = mgh, where m is the mass, g is the acceleration due to gravity (approximately 9.81 m/s²), and h is the height. In this case, since the weight of the object is given as 50 newtons, we can use this directly. The potential energy of the 50 newton object at a height of 30 meters is PE = 50 N × 30 m = 1500 joules.
