A ball thrown upward at a given speed will reach the ground with the same speed as the initial speed, regardless of the angle at which it is thrown.

Question

Neglecting air resistance, the principle of conservation of energy ensures that a ball thrown upward will return to the ground with the same speed it had when it was launched, regardless of the angle of launch. This is because the kinetic energy lost on the way up is converted into potential energy at the peak of its trajectory, which is then fully converted back into kinetic energy as it falls back to the ground.
