A car moved 60 km East, then 90 km East. What is the displacement it traveled?

• 30 km, West
• 60 km. East
• 150 km West
• 150 km East

What is the total displacement?
100 m/s        230 m/s
<------        --------->

• 30 m/s to the right
• 230 m/s to the right
• 130 m/s to the right
• This is a balanced force

The Pythagorean Theorem states that you can find Length of the Hypotenuse of a right triangle by finding the ...

• square root of the sum of the squares of the other two sides
• sum of the squares of the other two sides
• sum of the other two sides
• Inverse Tangent of the ratio of the other two sides

One way to write the Pythagorean Theorem is ... 

• a + b = c
• a² + b² = c
• a² + b² = c²
• a² * b² = c²
