Physics Question Please do Part A B and C

What is Ward's displacement vector? Give your answer in component form, using a coordinate system in which the y-axis points north. Express your answers using two significant figures separated by a comma. Revievw Ruth sets out to visit her friend Ward, who lives 60 mi north and 100 mi east of her. She starts by driving east, but after 10 mi she comes to a detour that takes her 15 mi south before going east again. She then drives east for 8 mi and runs out of gas, so Ward flies there in his small plane to get her TTy-82,-45 mi You have already submitted this answer. Enter a new answer No credit lost.

Answer 1

D_x = (10 + 8) mi D_y = -[15] = -15 mi Therefore r_x, r_y = 18, - 15 mi Vertical-bar r Vertical-bar = squareroot r_x^2 + r_y^2 = 23 mi theta = tan^-1 ( Vertical-bar r_x Vertical-bar / Vertical-bar r_y) = 50 degree
