A car travels 90 meters due north in 15 seconds. Then the car turns around and travels 40 meters due south.  What is the magnitude and direction  of the car's resultant displacement?  

• 40 metres, South
• 50 metres, South
• 50 metres, North
• 40 metres, North 

2. How are speed and velocity different?

• Speed involves how fast something moves while velocity does not.

• Velocity has a direction while speed does not.

• There is no difference between speed and velocity.

• Velocity has a magnitude while speed does not.

12. How are speed and velocity the same?

• Speed calculations involve distance and velocity calculations involve displacement.

• Velocity has a direction while speed does not.

• Speed and velocity measurements are exactly the same.

• Speed and velocity are both represented by the variable 'v' in formulas.

In the distance vs. time graph, what type of motion does the line represent? 

• Speed
• Velocity
• Acceleration
• Deceleration

Acceleration of an object happens when things ________

• slow down
• go faster
• change direction (turn)
• All of the above
