Question

Margaret walks to the store using the following path 0.630 mi west, 0.370 mi north, 0.180 mi east. assume north to be along the +y-axis and west to be along the -x-axis. what is the magnitude of her total displacement?​

Answer 1

Answer:

d = 0.583 mi

Explanation:

d = √((-0.630 + 0.180)² + 0.370²)

d = √(-0.450² + 0.370²) = 0.582580... = 0.583 mi

direction would be arctan(0.370/ -0.450) = 39.42780... = 39.4° N of W
