imagine you push a 50 kg crate with 200 N of force if friction pushes back with 100 N of force what acceleration does the crate have?

2m/s^2

Explanation:

So, if a crate moving in a direction is being pushed at 200 N, and being stopped by friction with a force of 100 N, this means that the crate has a total of 100 N of force in its direction. Since F = ma, we can say the acceleration is 100 N / 50 kg, or the object is accelerating at 2m/s^2
