Astudent throws a water balloon with speed v0 from a height h = 1.82 m at an angle 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. determine the magnitude of the balloon's initial velocity, v0, in meters per second.
