    A projectile is thrown obliquely into the air from origin of a reference frame with y-axis vertically upward and\[x-\]axis perpendicular to y then equation of motion has the form

    A)  \[y=ax+b{{x}^{2}}\]     

    B)  \[y=a{{x}^{2}}+b{{x}^{3}}\]

    C)  \[y=a+bx\]       

    D)  \[y=(a+b)x\]

    Correct Answer: A

    Solution :

    : For a projectile motion, the trajectory is a parabola. It is a first degree equation in y and second degree equation in\[x\]for a parabola. Hence the form of equation is \[y=ax+b{{x}^{2}}\]. Here a and b are constants.
