Question
82 In the overhead view of Fig.
5-65, five forces pull on a box of
mass m = 4.0 kg. The force magni-
tudes are F, = 11 N, F2= 17 N,
F; = 3.0 N, F, = 14N, and F; = 5.0 N,
and angle 0, is 30°. Find the box's
acceleration (a) in unit-vector nota-
tion and as (b) a magnitude and
(c) an angle relative to the positive
direction of the x axis.
