A block whose weight is 42.6 N rests on a horizontal table. A horizontal force of 34.1 N is applied to the block. The coefficients of static and kinetic friction are 0.640 and 0.390, respectively. Will the block move under the influence of the force, and, if so, what will be the block's acceleration? If the block does not move, give 0 m/s2 as the acceleration.
