Chapter 1.3, Problem 3aT

Choose a point before the turnaround and another after.

In the space below, draw the velocity vectors and label them $\stackrel{\to }{{\upsilon }_i}\text{and}\stackrel{\to }{{\upsilon }_t}$ .

Draw the vector that must be added to the velocity at the earlier time to obtain the velocity at the later time.

Is the name change in velocity that you used in sections I and II also appropriate for this vector?
