How a 100 kg crate is lifted to a height of 10 meters. At this height what is the potential energy of the crate?

The potential energy of the crate at a height of 10 meters is given by the formula PE = mgh, where m is the mass (100 kg), g is the acceleration due to gravity (9.81 m/s²), and h is the height (10 meters). Substituting the values, we get PE = 100 kg * 9.81 m/s² * 10 meters = 9810 Joules.
