    Answer: 750Kg

    Explanation:

    Recall that force is the product of the mass M, of an object moving at a uniform acceleration.

    i. e Force = Mass x Acceleration

    In this case, Mass = ?

    Force = 3.00 x 10^3 N = (3.00 x 1000N)

    = 3000N

    Uniform acceleration = 4.00m/s^2

    Force = Mass x Acceleration

    3000N = Mass x 4.00m/s^2

    Mass = (3000N/4.00m/s^2)

    Mass = 750Kg (The SI unit of mass is kilograms)

    Thus, the mass of the car is 750Kg
