Answer:
2m/s^2
Step-by-step 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
