1. The problem statement, all variables and given/known data A car that weighs 900 kilograms is driving around a racetrack, the radius of the racetrack is 100 meters. Thecar has a constant speed of 110 km/h. The friction coefficient between the tires and the track is 0.980. Decide: a) The car's acceleration b) The size of the friction 2. Relevant equations 3. The attempt at a solution I got a to 9.34 m/s2 which I believe is correct. I'm having a much harder time with b which I get to 8,65 kN which I know is incorrect. Please help! Thanks!
