Application +4 | -1

A bat and an insect are flying with velocities

\overrightarrow{{V}}_{\mathrm{BG}}

and

\overrightarrow{{V}}_{\text {IG }}

respectively with respect to ground (in unit vector

\hat{{i}}, \hat{{j}}

rotation)

\vec{V}_{\text {BG }}=3.5 \hat{{i}}+9.2 \hat{{j}}, \overrightarrow{\mathrm{V}}_{\mathrm{IG}}=-2.5 \hat{{i}}+{1 . 8} \hat{{j}}

Calculate the velocity of the insect with respect to bat.

View answer and explanation

Correct option: B

-6 \hat{\mathrm{i}}-7.4 \hat{\mathrm{j}}

Option B (

-6 \hat{\mathrm{i}}-7.4 \hat{\mathrm{j}}

) is correct because the relative velocity is calculated by subtracting the bat's velocity from the insect's velocity.
