To a stationary observer, a bus moves north with a speed of 10 m/s. a man inside walks toward the back of the bus with a speed of 0.4 m/s relative to the bus. what is the velocity of the man according to a stationary observer?

v = 9.6 m/s

Explanation:

Here we know that velocity is bus is

also the person inside the bus is moving in opposite direction with repect to bus at speed of 0.4 m/s

now we know that

now we know that

now we have

so velocity of man is 9.6 m/s in direction of bus with respect to stationary observer
