During a science experiment, Mr.Morris dropped a ball from a height of 150 m. The graph shows the distance the ball traveled from its original position to where it hit the ground. What does the graph tell you about the speed of the ball over time?

• The ball travels at a constant speed.

• The speed of the ball increases over time.

• The speed of the ball decreases over time.

• e speed of the ball increases at first, and then decreases as time increases.
