A train is traveling at a constant velocity of 12 m/s and travels 240 m. How much time did this take? (Answer in seconds and do not include a unit)

What is the velocity of the object between 2 and 5 seconds?

• 0 m/s

• 6.3 m/s

• 30 m/s

• 50 m/s

What is the acceleration of the object during interval C?

A car is traveling at 12.5 m/s when it sees a stop sign 430 m away. If the car begins breaking immediately and comes to a stop at the stop sign, what is the acceleration of the car. (Give the numeric answer only and do not forget the sign!)
