Acar at the indianapolis-500 accelerates uniformly from the pit area, going from rest to 335 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.

Acceleration,                                                          

Explanation:

It is given that,

Initial speed of the car, u = 0

Final speed of the car, v = 335 km/h = 93.05 m/s

Radius of the semicircular arc, r = 194 m

Distance covered by the car in the semicircular arc is,

The tangential acceleration of the car is given by the following formula as :

So, the tangential acceleration of the car when it is halfway through the turn is . Hence, this is the required solution.
