Work Step by Step

While the projectile will have a constant x-speed, its y-speed will not be constant, so its overall speed will not be constant. After all, there is a force (gravity) that is acting on the object with no opposing force. According to Newton's second law, this means that the object must be accelerating, meaning that its speed is not constant.
