Newton's Second Law:
* F = ma
Where:
* F is the net force (in Newtons, N)
* m is the mass (in kilograms, kg)
* a is the acceleration (in meters per second squared, m/s²)
Solving for Mass:
1. Rearrange the formula: To solve for mass (m), divide both sides of the equation by acceleration (a):
* m = F / a
2. Plug in the values:
* m = 12 N / 0.20 m/s²
3. Calculate:
* m = 60 kg
Therefore, the mass of the crate is 60 kg.
