Speed, Velocity & Acceleration quiz

A car's position in relation to time is plotted on the graph. What can be said about the car during segment B?

• The car travels for 80 seconds during segment B.

• The car has come to a stop and has zero velocity.

• The car is traveling faster during segment B than in segment C.

• The car is traveling with a constant velocity due to the flat line of the graph.

A train engineer started the train from a standstill and sped up to 5 m/s, she then rounded a corner at a constant speed. She then sped the train up to 10 m/s on the next straightaway. Next, the train chugged around another bend at 10 m/s, and then its speed slowed to 5 m/s after coming out of the bend. Finally, the train reached the station, and the engineer applied the brakes and brought the engine to a stop. How many times did the train accelerate?

• 2

• 4

• 5

• 6
