    Answer:

    Speed of the car around the circular path will be 12 m/sec

    Explanation:

    We have given mass of the car m = 1500 kg

    Radius of the curve r = 45 m

    Centripetal acceleration of the car a=3.2m/sec^2

    We have to find the speed of the car

    We know that centripetal acceleration is given by a=\frac{v^2}{r}, here v is car speed along the circular path and r is radius of the curve

    So 3.2=\frac{v^2}{45}

    v^2=144

    v = 12 m/sec

    So speed of the car around the circular path will be 12 m/sec
