15. Displacement and Distance Traveled Suppose a particle moves along a path in the plane so that its velocity at any time t is where v 1 and v 2 are integrable functions of t. The displacement from t = a to t = b is given by the vector The preceding vector is added to the position at t = a to get the position at t = b. The distance traveled from t = a to t = b is

16. Example Finding Displacement and Distance Traveled 4. A particle moves in the plane with velocity vector At t = 0, the particle is at the point (1, 5). a. Find the position of the particle at t = 4.

17. Example Finding Displacement and Distance Traveled 4. A particle moves in the plane with velocity vector At t = 0, the particle is at the point (1, 5). b. What is the total distance traveled by the particle from t = 0 to t = 4?
