Static and kinetic friction

You might need: Calculator


A 7.0kg box is at rest on a table. The static friction coefficient μs between the box and table is 0.40, and the kinetic friction coefficient μk is 0.10. Then, a 30N horizontal force is applied to the box.
What is the best estimate of the magnitude of the box’s acceleration?
Round the answer (if non-zero) to two significant digits.
