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

i don't know that i agree with that but what's the question ?

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
