<em>A student throws a water balloon with speed v0 from a height h = 1.8m at an angle θ = 29° above the horizontal toward a target on the ground. The target is located a horizontal distance d = 9.5 m from the student’s feet. Assume that the balloon moves without air resistance. Use a Cartesian coordinate system with the origin at the balloon's initial position.</em>
The time it takes for the balloon to reach the target is equal to the target distance divided by the horizontal component of the velocity :
where is the horizontal component of the velocity , and it is given by
