Question

Two cars a and b are moving a long a straight road in the same direction with velocities of 25 km/h And 40 km/h respectively find the velocity of car b relative to car A

Answer 1

relative velocity of b with respect to a= Vb- Va= 40-25=15km/h

Answer 2

Given :

Velocity of car A = 25 Km/hr

Velocity of car B = 40 Km/hr

To Find :

The velocity of car B relative to car A

Solution :

Relative velocity of car B with respect to car A ($V_{B/A}$) = V$_B$ - V$_A$

                                                                                        =  40 - 25

                                                                                        = 15 Km/hr

Therefore, Velocity of car B relative to car A is 15 Km/hr

What is relative velocity?

Relative velocity is defined as the apparent velocity with respect to another body that may be in motion.
