You pull on a 30 kg box with a horizontal force of 110 N to the right. (i) If there are no other forces acting on this box, what is the resulting acceleration? (ii) If the resulting acceleration of the block is only 1.6 m/s, what is the magnitude and direction of the frictional force acting on the block
The Attempt at a Solution
For (i) a- f/m and I got a=3.67
i have no idea how to solve for (ii) i thought it would f=m times a, but i have no idea where to start/solve any help, please?
