The position of a particle is represented by a vector i of 20 m long and directed with an angle of 45.0° (Fig. 2). a) Find the x and y components of the vector and express the position vector in components form using unit vectors. b) Can you determine the velocity of the particle at t=8s? Does the result Fig. 2 make sense?

In an attempt to escape a desert island, a castaway builds a raft and sets out to sea. The wind shifts a great deal during the day, and she is blown along the following straight lines: 2.50 km and 45.0 north of west, then 4.70 km and 60.0 south of east, then 130 km and 25.0 of west, then 5.10 km due east, then 1.70 km and 5.00 east of north, then 7.20 km and 55.0 south of west, and finally 2.80 km and 10.0 north of east. Use the analytical method to find the resultant vector of all her displacement vectors. What is its magnitude and direction?
