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.

the answer is mosques. they are an important part of islamic culture.

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
