A hard rubber ball is thrown level to the ground at a speed of 25 m/s and an initial height of 2.0 meters. Which best describes the resulting motion?

Answer 1

Since the ball is being thrown horizontally, it is moving in two directions, forwards and down. Initially, the ball starts moving forwards at 25 m/s without any downwards motion but as soon as it is released, gravity starts to accelerate the ball towards the ground. As it continues to move, its vertical speed is increasing due to gravity but its horizontal speed remains a constant 25 m/s since there is no force causing it to speed up or slow down in that directions. It will remain in the air until it has fallen 2 meters and hits the ground.
