What is the potential energy of a 2 kg rock resting at the top of a 10-meter high cliff? PEg= mgh

PEg= gravitational potential energy (energy due to position- Joules)

m= mass (kg)

h= height (m)

Which is an example of an exothermic process?

Ahorizontal force of 400.0 n is required to pull a 1760 n truck across the floor at a constant speed. find the coefficient of sliding friction.

Atypical jetliner lands at a speed of 146 mi/h and decelerates at the rate of (10.4 mi/h)/s. if the jetliner travels at a constant speed of 146 mi/h for 1.5 s after landing before applying the brakes, what is the total displacement of the jetliner between touchdown on the runway and coming to rest?
