Question

1. Consider two displacements, one of magnitude 3 m and another
of magnitude 4 m. Show how the displacement vectors
may be combined to get a resultant displacement of magnitude
(a) 7 m, (b) 1 m, and (c) 5 m.

Answer 1

if the displacement is in same direction then we get displacement=7m

if the displacement is in opposite direction then we get displacement=1m

if the displacement are perpendicular to each other then we get displacement=5m
