This question has two parts. First, complete Part A. Then complete Part B. Which of the following statements BEST supports your answer to Part A?

• A straight line on a speed vs time graph demonstrates a car at rest.

• A straight line on a speed vs time graph demonstrates a car at constant speed.

• A diagonal line on a speed vs time graph moving upward on the y-axis demonstrates a car slowing down.

• A diagonal line on a speed vs time graph moving downward on the y-axis demonstrates a car slowing down.

During a science experiment, a student dropped a metal ball from a height of 150 m. The graph shows the distance the metal ball traveled from its initial position to where it hit the ground. What information does the graph give you about the speed of the metal 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.

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

An image of a toy rocket and forces are shown below. Assuming the only two forces on the toy rocket are lift and gravity, which of the following combinations would result in the rocket moving upward?

• Lift= 5 Newtons / Gravity = 5 Newtons

• Lift = 3 Newtons / Gravity = 4 Newtons

• Lift = 5 Newtons / Gravity = 4 Newtons

• Lift = 4 Newtons / Gravity = 4 Newtons
