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:

hope this helps you to understand the solution

Answer 2

Answer:

The angle is 53.1°.

Explanation:

Given that,

Velocity of A = 3 km/h toward west

Velocity of B = 4 km/h toward north

We need to calculate the angle

The velocity of A relative to B is at an angle

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

Where, $v_{A}$= velocity of A

$v_{B}$= velocity of B

Put the value into the formula

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

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

$\theta=53.1^{\circ}$

Hence, The angle is 53.1°.
