9 calculate balanced rock has a mass of about 36,000 kg. if the acceleration due to gravity is 9.8 m/s², what is the force that the rock is exerting on its pedestal?

Answer

# Explanation: ## Step1: Recall the force - mass - acceleration formula According to Newton's second law, $F = ma$, where $F$ is the force, $m$ is the mass, and $a$ is the acceleration. In the case of an object on the Earth's surface, the force exerted on the pedestal is the weight of the object, and $a = g$ (acceleration due to gravity). ## Step2: Substitute the given values We are given that $m=36000\ kg$ and $g = 9.8\ m/s^{2}$. Substitute these values into the formula $F=mg$. $F=36000\times9.8$ $F = 352800\ N$ # Answer: $352800\ N$
