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: Zero Non-Zero 2) Explain your answer. Because there is no acceleration. 3) The net force in the vertical direction on the block in Animation 1 is: Zero Up Down 4) Explain your answer. Because there is a constant velocity meaning no acceleration. 5) In both Animations, the frictional force on the block is acting in which direction? Up Down Left Right 6) What is the magnitude of the force applied on the block by the finger in Animation 1? 35 N 49 N 56 N 98 N 7) Explain how you calculated the above answer. 8) The net force in the vertical direction on the block in Animation 2 is: Zero Up Down 9) What is the magnitude of the force applied on the block by the finger in Animation 2? 39 N 45 N 54 N 68 N 10) Explain how you calculated the above answer.
