Answer:

Answer

a.

v

BA

=

v

B

-

v

A

Hence, velocity of train B w.r.t train A is 144 km/h toward south.

b. Velocity of ground w.r.t. B

v

g,B

=v

g

−v

B

= 0 - 90$$

v

g,B

= -90 km/h

Hence, velocity of ground w.r.t train B is 90 km/h towards north.

c.

v

=

v

m,A

+

v

Ag

= 18 - 54 = -36 km/h

Hence, velocity of monkey will be 36 km/h toward north.

answer :10kmh/h north

Explanation:

this is because. in a straight line.

velocity =speed.

according to the question

speed of train (a) =40km/h

speed of train (b) =30km/h

velocity of train ( a) =40km/h

velocity of train (b) =30km/h

relative velocity =velocity of (a)-(b)...

40km/h-30km/h=10km/h
