• All of the above are examples of acceleration.

One jet is flying east at 880 km/hr and another plane is traveling north at 880 km/hr. Do they have the same velocity and speed?

• Yes, they have the same speed and velocity.

• No, they have the same speed but different velocities.

• No, they have the same velocities but different speeds.

• No, their speeds and velocities are different.

What is the velocity of the car between 9 seconds and 15 seconds?

• 0.33 m/s away from the starting point

• 0.33 m/s back to the starting point

• 3 m/s away from the starting point

• 6 m/s back to the starting point
