Learning Goal: Suppose an object has an initial velocity v₁ at time t; and later, at time tf, has velocity Vf. The fact that the velocity changes tells us the object undergoes an acceleration during the time interval At = tf — t₁. From the definition of average acceleration, Figure a = 15 Vf - Vi tf-ti = Δύ At we see that the acceleration vector points in the same direction as the vector Av. This vector is the change in the velocity Av = f - Vi, so to know which way the acceleration vector points, we have to perform the vector subtraction of — V₁. This Tactics Box shows how to use vector subtraction to find the acceleration vector. - 9 1 of 1 Part B Below is another motion diagram for an object that moves along a linear path. The dots are separated by equal intervals and represent the position of the object at five subsequent instants. The vectors V21, 32, 43, and 54 represent the average velocity of the object during the four corresponding time intervals. Draw the velocity vectors…
