Question

a man walks foward on a bus. to a stationary obserrver, the bus moves east at a speed of 13 m/s if the man moves 0.7 m/s east relative to the bus. what is his velocity in the frame of reference of a stationary observer?

Answer 1

In This question we have given that

velocity of bus=
`13(m)/(s)` towards East

Velocity of Man=
`0.7(m)/(s)` Towards East

It means Both are moving in the same direction

Therefore velocity of man in the frame of reference of a stationary observer is given as=velocity of bus+velocity of man

=
`13(m)/(s)+0.7(m)/(s)`

=
`13.7(m)/(s)` towards east

Therefore, Therefore velocity of man in the frame of reference of a stationary observer is
`13.7(m)/(s)` Towards east
