Question

A lightning bug flies at a velocity of 0.25 m/s due east toward another lightning bug seen off in the distance: A light easterly breeze (coming from the east) blows on the bug at a velocity of 0.25 m/s. What is the resultant velocity of the lightning bug?

A. 0.00 m/s.
B.0.25 m/s East.
C.0.25 m/s West.
D.0.5 m/a East

Answer 1

Consider velocity due east as along the positive x-axis.

Therefore.
The velocity of the bug is, v = + 0.25 m/s
The easterly breeze has velocity, u = - 0.25 m/s

The resultant velocity of the bug is
v + u = 0.25 + (-0.25) = 0.25 - 0.25 = 0.00

Answer: A. 0.00 m/s
