Question

An object A is moving with 5 m/s and B is moving with 20 m/s along +x axis. Velocity of B with respect to A is
(1) 25 m/s
(2) -15 m/s
(3) -25 m/s
(4) 15 m/s ​

Answer 1

Explanation:

Velocity of B, A and the difference in the velocities are given as follows.

v

B

=+20m/sv

A

=+5m/sv

BA

=v

B

−v

A

=+15m/s

Hence, the velocity of B with respect to A is 15 m/s.
