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?
