A car at the Indianapolis-500 accelerates uniformly from the pit area, going from rest to 340 km/h in a semicircular arc with a radius of 194 m.
Determine the tangential acceleration of the car when it is halfway through the turn, assuming constant tangential acceleration. m/s2
Determine the radial acceleration of the car at this time.
m/s2
If the curve were flat, what would the coefficient of static friction have to be between the tires and the roadbed to provide this acceleration with no slipping or skidoding?
A 2.16 kg block on a horizontal floor is attached to a horizontal spring that is initially compressed 0.0320 m. The spring has force constant 840 N/m.
