Question

A student bikes to school by traveling first dN = 1.10 milesnorth, then dW = 0.400 miles west, and finally dS = 0.200 miles south.

Similarly, let d⃗ W be the displacement vector corresponding to the second leg of the student's trip. Express d⃗ W in component form.

Express your answer as two numbers separated by a comma. Be careful with your signs.

Answer 1

Displacement vector is the vector from the initial position of an object to the final position of the object. For the second leg of the trip the student moves 0.4 miles west from the position at the end of first leg. Considering the west direction as negative x- axis, the displacement vector in component form can be written as,

dW =(-0.4, 0.0)
