For this lab there are two different animations to view. You can view each of the animations by clicking on "Animation 1" or "Animation 2" below the animator box. In both animations a force is being applied by a finger on a 2kg block pushing against the wall; however the force applied by the finger is different in each case. The coefficient of static and kinetic friction between the block and the wall is .5 and .4 respectively. 1) The net force in the horizontal direction on the block in Animation 1 is:
