Answer:

[tex]a=-4.5,b=v,c=0[/tex]

Step-by-step explanation:

The given formula for the height of the projectile is

[tex]h=-4.9t^2+vt[/tex]

This is a quadratic equation in [tex]t[/tex].

To solve for t, we set the equation to zero to get;

[tex]-4.9t^2+vt=0[/tex]

where [tex]a=-4.9[/tex] is the coefficient of [tex]t^2[/tex], [tex]b=v[/tex] is the coefficient of [tex]t[/tex], and [tex]c=0[/tex] is the constant term.

The correct answer is C
