How Can You Verify and Complete Parametric Equations for Projectile Motion?

[DomoArigato12]

Homework Statement

Given0-1.6, time in air - 3.02 s, horizontal distance thrown - 10m
Solve:V0 and write parametric equations for x(t) and y(t) - the horizontal and vertical positions of the ball

Homework Equations

h(t)=-4.9t^2+V0t+h0

The Attempt at a Solution

for V0 I got 14.268
when trying to write y(t) I got y(t)=-4.9t^2+14.268t+1.6

I need help verifying that what I got is correct, if any additional information is needed write. I also need help writing x(t), the horizontal position of the ball equation

How did you get 14.268 for V0?

For writing x(t), what is true about the velocity component in the x direction?
