Question

To a stationary, a bus moves south with a speed of 15 m/s. a man inside walks toward the front of the bus with a speed of 0.2 m/s relative to the bus. What is the velocity of the man according to a stationary observer?

Answer 1

it is 15.2 m/s South.

Answer 2

Answer:

Velocity of man with respect to stationary observer is 15.2 m/s

Explanation:

It is given that, to a stationary, a bus moves south with a speed of 15 m/s. A man inside walks toward the front of the bus with a speed of 0.2 m/s relative to the bus. We have to find the velocity of man according to stationary observer.

The velocity of bus and man are in same direction. So, the velocity of man with respect to stationary observer will be :

$v_{m,o}=v_b+v_m$

$v_{m,o}=15\ m/s+0.2\ m/s$

$v_{m,o}=15.2\ m/s$

Hence, this is the required solution.
