Question: A food particle from your breakfast takes a circuitous path through your digestive system. Suppose its motion over a period of time can be represented

A food particle from your breakfast takes a circuitous path through your digestive system. Suppose its motion over a period of time can be represented by the four displacement vectors depicted in FIGURE 3-49. Let the vectors have magnitudes A = 8.0 cm, B = 16 cm, C = 23 cm, and D = 5.6 cm.

(a) What is the total displacement of the food particle? Give its direction relative to the direction of vector A.

(b) If the average speed of the particle is 0.010 mm/s, what is its average velocity over the time interval of the four displacements?

D A
