Question

Let two bodies 'A' and 'B'.
The body 'A' has velocity of 20m/s whereas 'B' has 10m/s.

What will be the sign(positive or negative) of velocity of 'B' with respect to 'A'?

What will be the velocity of 'A' as seen by 'B' ?​

Answer 1

Answer:

$\huge\underbrace\mathfrak\pink{Answer}$

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

VA=+10m/sv

VB=−12m/sv

VAB=VAVA-VB.

=+22m/s

=+22m/sHence, the velocity of A with respect to B is 22 m/s.

I hope this helps you......

Answer 2

Answer:

ANSWER

ANSWER

Answer is A.

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

v

A

=+10m/sv

B

=−12m/sv

AB

=v

A

−v

B

=+22m/s

Hence, the velocity of A with respect to B is 22 m/s.
