(I) A car is driven 225 km west and then 98 km southwest (45°). What is the displacement of the car from the point of origin (magnitude and direction)? Draw a diagram.

I) (a) We will start with displacement, the straight line (as the crow or airplane flies distance) covered by a moving object starting from an initial location and arriving at a final location. Vector quantities will be written in bold face i.e. A. Consider the situation of an ant that travels east, i.e. along the x axis, for 8 cm then travels northeast, i.e. 45° from the x axis, for 11 cm. Represent each leg of this journey by a vector on your graph paper. Vectors are written as arrows with the direction going from the tail of the arrow to the head of the arrow and the length of the arrow proportional to the magnitude (size) of the vector. Indicate the first part of the journey by an arrow of length 8 cm whose tail starts at the origin of your graph and whose head is at 8 units along the positive x direction. Call this vector A which is the displacement of the first part of the ant's journey. Now starting at the head of A draw a vector B which represents the second part of the ant's…

The figure shows the path taken by a drunk skunk over level ground, from initial point i ta final point f. The angles are 0, - 31.0, 0, - 46.0, and 0, - 84,0, and the distances ared, - 5.20 m, d, - 7.10 m, and dy - 12.0 m. What are the (a) magnitude and (b) angle of the skunk's displacerment fromi to f? Give the angle as a pusitive (cuunterckockwise) ur nugative (clotkwise) angle of magnitude less than 180', measured from the +xdlirection. (a) Number Units (b) Number Unils
