## Homework Statement

A 2.0 kg box is pulled along a horizontal plank by a 10N force parallel to the direction of motion. The rate of acceleration is 0.50 m/s^2. Find the coefficient of kinetic friction.

I think we use the formula: coefficient of friction = F (so 10) / N.

But I am not sure how to use the acceleration and the N variable.

## Homework Equations

F - μk mg = ma

10 - 2(9.8)μk = 2 x 0.5

Would this be the correct way to go?

Thanks!
