work help! I'm stuck and about to kill myself
A car at the Indianapolis-500 accelerates uniformly from the pit area, going from rest to 320 km/h in a semicircular arc with a radius of 192 m.
Determine the tangential acceleration of the car when it is halfway through the turn, assuming constant acceleration.
m/s^2(tangent to the path)
(I know that the equation is equal to mv2/r but how do i set it up. what is the difference between tangent and toward the center.)
Determine the radial acceleration at this time.
m/s^2 (toward the center of the path)
(It is rev/sec and multiply. i got 3.7m/s^2)
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 skidding?
(mu=fN I got all these other formulas and forces on the car and put them together, and i got .48 but it's wrong)
