## Homework Statement

A woman walks 132 m in the direction 41° east of north, then 170 m directly east. Find (a) the magnitude and (b) the angle (from due east) of her final displacement from the starting point. (c) Find the distance she walks.

## Homework Equations

??

## The Attempt at a Solution

i think it is wrong please help

N displacement of leg 1 = (cos41) x 132m., = 99.62m.

E displacement of leg 1 = (sin 41) x 132m., = 86.6m.

Total N displacement = 99.62m.

Total E displacement = (170 + 86.6) = 256.6m.

a) Magnitude = sqrt. (99.62^2 + 256.6^2), = 275.26 m.

b) Sin L = (99.62/275.26), so L = 22.22 degrees, N of E.

c) (132 + 170) = 302 m.
