Consider a particle subject to the forces shown in Figure 1, where the forces have magnitudes
Fi = 18N,
F2 = 5N,
F3 = 11N,
40°, and az = 0° for F1, F2,
and the angles with respect to the horizontal are a1
and F3 respectively.
65°, a2 =
(a) Find the resultant force and calculate its magnitude and direction (relative to the
positive x-axis).
(b) This resultant force now acts on an object (modelled as a particle) of mass 8 kg. Find
the acceleration and calculate its magnitude.
