Physics in Wegmans

Sign in to follow this  


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


d=3.5 ft

Vi=0 m/s


Using d=Vit+1/2at^2, I solved for t.


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 .44s

That is an excellent reaction time... just remember when doing your calculations that you need to convert 3.5 feet to meters first! (3.5 feet = 1.07m)

Or, to be more accurate, since the box only fell about 2.5 feet, the displacement of the box was closer to 0.76m. Now how fast was your reaction time? :egg)
