A Physics teacher, Susan, drove to her high school which is located 15km East from her house. After school, she drove to her children's elementary school which is 10 km South from her high school. Then, she drove to a grocery store, located 15km West from the elementary school. Finally, she drove back to home with her kids and several grocery bags. Explain whether the following statements are true or false: The total distance she traveled from her house to elementary school is 18 km. The magnitude of the displacement vector from the high school to the grocery store is 25 km. The magnitude of the displacement vector for the whole trip is 50 km. The magnitude of the displacement vector from her house to the grocery store is 10 km.

a bug starts at the center of a 12 inch phonograph record and crawls along a straight radial line to the edge. While this is happening, the record turns through an angle of 45 degrees. Draw a sketch of the situation and describe the magnitude and direction of the bug's final displacement from its starting point
Caleb left home and traveled toward the city A at an average speed of 61.1 km/h. Some time later, Kim left traveling in the opposite direction with an average speed of 48.6 km/h. After Caleb has traveled for 1.46 hours they were 144 km apart. Find the number of minutes Kim traveled. Round off only on the final answer expressed in three decimal places.

Bruce begins 7 kilometers to the north of town and rides his bike along a straight trail which leads to a park 3km west of town. It takes him 20 minutes to cover this distance. Write a vector in component form that describes his ride while also finding the magnitude and direction of this vector. Also, find the component of Bruce's motion which is in the direction of SW using a unit vector that uses both forms of the dot product (algebraic and geometric), then write parametric equations expressing his motion with the town being represented by the origin and t=0 being his starting point. Using these equations, what is his position after 5 minutes? Then eliminate the parameter to get a rectangular equation for this linear path and verify algabraically amd graphically that this equation represents the line.
