• The cart moved toward the starting point at a speed of 3 m/s between 7 s and 12 s.

• The cart moved 11 m toward the starting point between 8 s and 10 s.

• The cart moved away from the starting point at a speed of 1 m/s for 2 s.

The graph below shows distance over time. Which of these situations could be represented by this graph?

• A student walks 1.5 km to a friend’s house in 40 minutes. The two students then walk another 1.5 km to school in 20 minutes.

• A student walks 1.5 km to a friend’s house in 20 minutes. The two students then walk another 1.5 km to school in 40 minutes.

• A student walks 1.5 km to a friend’s house in 30 minutes. The two students then walk another 1.5 km to school in 30 minutes.

A meteor moving 468 km per minute traveling in a south-to-north direction passed near Earth in 2013. Because the meteor was only 45 m wide and was 27,700 km above Earth’s surface, it was not visible without the aid of a telescope. Which statement describes the meteor’s motion?

• Its velocity was 7.8 km/s northward.

• Its acceleration was 468 km/s2.

• Its speed was 468 km/s northward.

• Its acceleration was 7.8 km/s2.
