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.

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
