I am having trouble with this problem:(adsbygoogle = window.adsbygoogle || []).push({});

A block whose weight is 50.0N rests on a horizontal table. A horizontal force of 25.0 N is applied to the block. The coefficients of static and kidnetic friction are 0.510 and 0.350 respectively. Will the Block move under the influence of the force and if so, what will be the block's acceleration?

What I have so far:

1. Fs=mu sN

=0.510*50

=25.5 N

25.5 N>25.0 N, therefore the block will move under the influence of the force.

2. Finding acceleration

I know I have to find the net force then use that in the second law equation. How do I do that.

I have kinetic force=17.5, mass=50/9.8=5.10 kg.

Please help!
