Question

. Car A moving at 20 m/s on a straight road is ahead of car B moving in the same direction at 15 m/s. The velocity of B relative to A is ​

Answer 1

Answer:

The velocity of car AvA=10 m/s

The velocity of car B vB=6m/s

The relative velocity is the difference between both velocities.

The formula of the relative velocity is defined as

The velocity of A relative to B is

vAB=vA-VB

vAB=10-6=4M/S

The velocity of B relative to A is

vAB=vB-VA

vBA=6-10=-4 m/s

Hence, The velocity of A relative to B and vice versa is 4 m/s and -4 m/s.

Answer 2

Explanation:

The velocity of car AvA=20 m/s

The velocity of car B vB=15m/s

The relative velocity is the difference between both velocities.

The formula of the relative velocity is defined as

The velocity of A relative to B is

vAB=vA-VB

vAB=20-15=5M/S

The velocity of B relative to A is

vAB=vB-VA

vBA=15-20= -5 m/s

Hence, The velocity of A relative to B and vice versa is 5 m/s and -5 m/s.
