1. The problem statement, all variables and given/known data A 2500 kg car starts from rest and travels along a circular track with a radius of 55.0 meters. The car starts out at a position due East of the center of the track, heading due North initially around the track, which is counterclockwise. The car increases its speed by 105 m/s every minute around the track. How fast is the car traveling when it is 1/4 of the distance around the track? State the car's tangental velocity. 2. Relevant equations v=2*pi*r/period 3. The attempt at a solution I am unsure of how to begin this problem when I'm looking for only 1/4 of the distance. I'm also having a hard time finding the period of one full rotation around the track. Any help would be appreciated! Thanks.
