* Force is dependent on acceleration: Force (F) is calculated using Newton's second law of motion: F = m * a, where:
* F is force (in Newtons)
* m is mass (in kilograms)
* a is acceleration (in meters per second squared)
* Unknown acceleration: You only know the force (147 N). To find the mass, you need to know the acceleration acting on the rock.
Example Scenarios:
* Rock falling: If the rock is falling freely due to gravity, its acceleration is approximately 9.8 m/s². In this case, you could calculate the mass:
* m = F / a = 147 N / 9.8 m/s² = 15 kg
* Rock at rest: If the rock is sitting still, its acceleration is 0. Therefore, the force it produces is also 0, regardless of its mass.
To find the mass of the rock, you need more information, such as:
* The acceleration it's experiencing.
* The situation it's in (e.g., falling, being pushed, at rest).
