Question

Person A is moving towards west with speed 3 km/h
and B is moving towards north with speed 4 km/h.
Then the velocity of A relative to B is at an angle of​

Answer 1

Answer:

The angle of velocity of A relative to B is 36.8°.

Explanation:

Given that,

Velocity of  A $v_{A}= 3\ km/h$

Velocity of B $v_{B}= 4\ km/h$

We need to calculate the angle of relative velocity of A relative to B

Using formula of angle

$\tan\theta=\dfrac{v_{A}}{v_{B}}$

$\tan\theta=\dfrac{3}{4}$

$\theta=\tan^{-1}\dfrac{3}{4}$

$\theta=36.8^{\circ}$

Hence, The angle of velocity of A relative to B is 36.8°.
