How to draw part B?

Part B Learning Goal: To practice Tactics Box 4.1 Finding the Acceleration Below is another motion diagram for an object that moves along a curved path. The dots Vector. represent the position of the object at five subsequent instants, t1, t2, t3, t4, and t5. The vectors 121, U32, 143, and 154 represent the average velocity of the object during the four Suppose an object has an initial velocity vi at time corresponding time intervals. Draw the acceleration vectors a31 and a53 representing the ti and later, at time tf , has velocity of . The fact that changes in velocity of the object during the time intervals At31 = t3 - t1 and the velocity changes tells us that the object At53 = t5 - t3, respectively. undergoes an acceleration during the time interval At = tf - ti. From the definition of acceleration, Draw the vectors starting at the appropriate black dots. The location, orientation, and length of the vectors will be graded. a = of - vi If - ti At " we see that the acceleration vector points in the + same direction as the vector Av. This vector is the Figure
