Physics in Wegmans

In Wegmans today I dropped a box of crackers on the floor as i was grabbing them off the shelf. The box weighed about .5 kg and was about 3.5 ft up on the shelf when in fell. Using simple kinematics, I realized it did not take very much time to fall to the ground. a=9.81 m/s^2 t=? d=3.5 ft Vi=0 m/s Vf=/ Using d=Vit+1/2at^2, I solved for t. t=.84s The funny part is that I caught the box of crackers about a foot above the ground. This makes my reaction time very fast:) ...approximately .
