Question

Chapter 03, Problem 070 A woman walks 177 m in the direction 35 east of north, then 162 m directly east. Find (a) the magnitu

Answer 1

Answer #1

a)

Dx = 162 + 177 sin 35 = 263.52

Dy = 177 cos 35 = 145

magnitude

D^2 = Dx^2 + Dy^2

D = 300.77 m

========

b)

phi = arctan ( Dy/Dx) = 28.82

========

c)

d = 177 + 162 = 339 m

=======

Comment in case any doubt, will reply for sure.. Goodluck
