Matching Velocity Time Graph Scenarios

For the graph of the story : a student is walking home from school and stops to talk to a friend. While talking, he realizes that he forgot his bike at school and goes back to get it. He then rides his bike home. Which part matches up with Line segment A?

• Walking home from school

• Stops to talk to a friend

• Goes back to school

• Rides his bike home

• None of them

Between which time intervals does the object speed up/increase velocity?(velocity moves away from 0 m/s point)

• 0-10 sec and 40-55 sec

• 15-30 sec and 40-55 sec

• 0-10 sec and 30-40 sec

• 15-30 sec and 30-40 sec

• The distance travelled by the object.

• The acceleration of the object.

• The mass of the object

Part C of the graph is from 35s to 55s. Which of these statements is true about Part C?

• The object is at rest.

• The object is accelerating (its velocity is increasing)

• The object is decelerating (its velocity is decreasing)

• The object is moving at a constant velocity.
