Question

1. a mosquito flying at 3 m/s encounters a 3 - m/s breeze blowing in the same direction, which gives it a resulting speed over the ground of

a) 0 m/s.
b) 3 m/s.
c) 4 m/s.
d) 6 m/s.

Explanation:

Step1: Identify velocities

The mosquito's velocity $v_m = 3$ m/s and the breeze velocity $v_b=3$ m/s in the same - direction.

Step2: Calculate resultant velocity

When two velocities act in the same direction, the resultant velocity $v = v_m + v_b$. So, $v=3 + 3=6$ m/s.

Answer:

D. 6 m/s
