Question

Balanced Rock has a mass of about 36,000 kg. If the acceleration due to gravity is 9.8 m/s², (9.8 squared) what is the force that the rock is exerting on its pedestal? Include labels.
HINT: Remember Newton's second law, F=MA.

Answer 1

The force that the rock is exerting on its pedestal is just the weight of the rock.

                           Weight  =  (mass)  x  (acceleration of gravity)

                                         =    (36,000 kg)  x  (9.8 m/s²)

                                         =    (36,000  x  9.8)  kg-m/s²

                                         =          35,280 newtons
