A car at the Indianapolis 500 accelerates uniformly from the pit area, going from rest to 250 km/h in a semicircular arc with a radius of 230 m.
Determine the tangential and radial acceleration of the car when it is halfway through the turn, assuming constant tangential acceleration.
v2= 250km/h --> 69.44m/s
The Attempt at a Solution
(.302)2= 02 + 2 ([tex]\pi[/tex]/2) [tex]\alpha[/tex]
[tex]\alpha[/tex] = .02903 radan/s2
I got this for my TANGENT: (230m)(.02903radan/s2) = 6.68m/s2
and this is my RADIAL:[tex]\alpha[/tex] = 0.0290m/s2
I'm not sure if I did the problem right. My answers seem wrong. Please help me =]
