I believe I have some misconceptions regarding this topic. But here goes: I need some help to make sense of an experiment where I sling an object away with a rubber band, with a force of 5 N.
The object is put onto a surface, behind a rubber band. A thread is suspending the rubber band. The thread is then burnt with a match, and the object is released. Upon this, the object have friction with the surface and the air. It flies for 0,5 seconds and reaches a destination at 0,5 meters.
My data is an object weighing 0,05 kg and an external force of 5 N.
Using the formula a = F/m I land on an acceleration of 100 m/s^2.
However, the object does not move further than 0,5 meters, and it travels in 0,5 seconds. Which gives a speed of 1 m/s. And 100 m/s^2 seems outrages.
So how can I include wind resistance and friction into this little experiment, to make more sense?
Or should one simply state that without any other forces acting upon the object, it's acceleration is 100 m/s^2 ?
Thanks in advance!
