Ok I tried the Latex thing but I couldn't figure it out so i'll just write normally.
For the acceleration I used a = v2 / r = 30.52 / 100 = 9,34.
The second one is the one I'm sure must be wrong but I don't know what else to try. I'm using the equation for kinetic friction fk=\muk*n...
Homework Statement
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...
