Here, we have
x = 12 m ; y = 5 m ; z = 6m
Then, resultant vector is given by,
r = (x2 + y2 + z2 ) 1/2
= ( 122 + 52 + 62)1/2
= (205)1/2
= 14.31 m
Show that if , then where are the three vectors lying on the plane.
Here,
i.e.,
Hence,
Examples of mtion in two dimensions are:
(i) Motion of a football player in a ground.
(ii) Projectile motion.
