A 2.0 kg box of snickers is attached to a spring and placed on a 65 inclined plane hanging at rest. The spring has a spring constant of 20 N/m. The coefficient of static friction between the box and the board is 0.25. You want to set a trap to fire the snickers upwards just after your friend touches the box, so you pull the box further down the incline and release the box. The box remains at rest, held in place by the friction force and on the brink of slipping. (a) Determine the total elongation of the spring measured from its relaxed length. m Note that the box has a tendency to be pulled up the incline by the stretched out spring but is not moving, draw an accurate FBD. 2.0 kg 650 Figure (b) If the coefficient of friction was increased and the block was placed on the incline at the same elongation as part 'a', how would the friction force acting on the box be impacted? Decrease Remain the same Increase
