What is the mass of a falling rock accelerating at 9.8 m/s² if the rock produces 147 N of force?
To find the mass of the falling rock, we can use Newton's second law of motion which states that Force (F) equals mass (m) times acceleration (a).
Therefore, the equation can be written as:
F = m * a
Given that the force produced by the rock is 147 N and the acceleration is 9.8 m/s^2, we can plug these values into the equation to solve for the mass:
147 N = m * 9.8 m/s^2
m = 147 N / 9.8 m/s^2
m = 15 kg
Therefore, the mass of the falling rock is 15 kg.
