Which equation would best solve the following problem?

rita hits a tennis ball with an initial velocity of 15 meters/sec. when she hits the ball, it is one meter above the ground. how long will it take for the ball to hit the ground?
question 1 options:

–16t^2+ 15t + 1 = 0

–4.9t^2 + 15t = 1

–4.9t^2 + 15t + 1 = 0

4.9t^2 + 15t + 1 = 0
