Description
This is a simulation of a popular physics lab experiment. Two rolls of toilet paper are to be dropped. One will just drop due to gravity. The end of the other roll is held as the roll drops, causing the roll to rotate as it falls. This results in the two rolls having different accelerations. It is your job to figure out the height from which the rotating roll should be dropped so that it reaches the ground at the same exact time that the free-falling roll hits.
