What is the "given" here?

• Δx = 13 m
• x_i = 13 m
• v = 13 m/s
• t = 13 m

A car travels 14 meters in 7 seconds. How fast was the car going?

• v = 0.5 m/s
• v = 14.7 m/s
• v = 21 m/s
• v = 2 m/s

What are the units for acceleration?

• m/s
• m/s²
• m
• s/m

which two variables are vectors with magnitude and direction

• speed, velocity
• velocity, displacement
• distance, mass
• speed, distance

You are given a distance time graph of the motion of an object.  How would you determine the speed of the object?

• just read the graph
• take the slope of the graph
• speed will always = 0
• it can not be done

Δ

• take the slope
• product
• change in
• exponent
