Question

Two particles A and B are moving from along the y-axis at velocities 25 m/s and 30 m/s respectively. What is the relative velocity of particle A with respect to particle B?​

Answer 1

Above 2 pics are your correct answer.

Answer 2

Given: Two particles A and B are moving from along the y-axis at velocities 25 m/s and 30 m/s respectively.

To find: Relative velocity of particle A with respect to particle B

Explanation: Relative velocity of a body A with respect to another body B is the velocity of A when the body B is taken as the reference.

Let the velocity of A be v1, velocity of B be v2 and v be velocity of A with respect to B.

Now,

v1 = 25 m/s

v2 = 30 m/s

The formula of relative velocity of A with respect to B is :

v= v1 - v2

= 25-30

= -5 m/s

Therefore, the velocity of particle A with respect to particle B is -5 m/s.
