Vectors, Scalars, Distance, Displacement

A cat walks 3 meters west toward a laser, then jumps 5 meters due south of the laser when it sees a thing. What is the total distance the cat has traveled (to the nearest tenth)?

• 3.0m

• 5.0m

• 8.0m

• 5.8m

Which of the following is NOT a vector?

• 
• 
• 
• x

You walk 80m east on FM 518 to get some Whataburger. After getting there, your friend texts you that Red River is giving out free stuff so you head the 65 m south there. After that, you decide to head to the gas station for a nice drink to cool down, you head the 80 m west there. Suddenly you realize you forgot your wallet at school, you wonder, "how did I buy all that stuff?" and you run the 65m north back. What is your total displacement?

• 0m

• 290m

• 518m

• 80m

Which is NOT accurate about our GLX and motion sensor set up from the lab?

• The GLX displayed graphs of position vs time

• The motion sensor detected the distance of an object from it

• The motion sensor was accurate when using cars and hands

• The GLX needs to be connected to a laptop to work

How was the graph created?

• Keeping the car steady, moving it away from the sensor at a constant speed, holding it still for a little while, then moving it back toward the sensor

• Keeping the car steady, moving it away from the sensor slowly after first and then faster, holding it still for a little while, then moving it back toward the sensor

• Keeping the car steady, moving it away from the sensor quickly at first then slowly, holding it still for a little while, then moving it back toward the sensor

• Computers hooked up to a science machine

Here are ten free points!

• Theyr'e not here

• Are they here?

• Ummm

• But seriously, they're right here
