A car moves along a straight street. The car’s initial position at time t1 is given by a position vector x! . The car’s later position vector is x2! at time t2. Suppose x1! = 700 miˆ . and x2! =400miˆ.
a. If t2 – t1 = 3.0 seconds, what is the car’s average speed (assuming the car only moved in one direction)?
b. What was the car’s average velocity?

Below is a motion diagram for an object that moves along a linear path. The dots represent the position of the object at three subsequent instants, t1, t2, and t3. The vectors v⃗ 21 and v⃗ 32 show the average velocity of the object for the initial time interval, Δt21=t2−t1, and the final time interval, Δt32=t3−t2, respectively. Draw the vector −v→21 and the acceleration vector a⃗ representing the change in average velocity of the object during the total time interval...
