Which equation would best help solve the following problem?

Martina hits a volleyball ball upward with an initial velocity of 13 meters/sec. When she hits the ball, it is one meter above the ground. How long will it take the ball to hit the ground?

A.
–4.9t^2 + 13t + 1 = 0

B.
–4.9t^2 + 13t = 1

C.
4.9t^2 + 13t + 1 = 0

D.
–16t^2+ 13t + 1 = 0
