4. If the determinant delta of a quadratic equation is positive, the equation has two real roots. If the determinant is negative, it has two imaginary roots. In this case, delta=b^2-4ac=(-1)^2-4*1*4=-15. Therefore, this equation has two imaginary roots.
We know that According to Newton's Second Law that :
Force acting on an object is equal to the Mass of that Object multiplied by the Acceleration of that Object.
Given Mass of the Car as : 2000 kg
Acceleration of the Car as : 2 m/s²
Force required to move the Car = 2000 × 2 = 4000 Newton
