A 625-kg racing car completes one lap in 14.3 s around a circular track with a radius of 55.0 m. The car moves at constant speed.
(a) What is the acceleration of the car?

  • physics - ,

    d = 2pi*r,
    d = 6.28*55 = 345.6m = Linear distance,

    d = 0.5*at^2 = 345.6 m,
    0.5a*(14.3)^2 = 345.6,
    102.2a = 345.6,

    a = 345.6 / 102.2 = 3.38 m/s^2.
