A student throws a water balloon with speed yo from a height h = 1.74 m at an θ = 29° above the horizontal toward a target on the ground.
A student throws a water balloon with speed yo from a height h = 1.74 m at an θ = 29° above the horizontal toward a target on the ground. The target is located a horizontal distance d= 7.5 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.
