Aman jogs at a velocity of 2.5 m/s west for 1,200 s. he then walks at a velocity 1.0 m/s east for 500 s and then stops to rest . what is the displacement of man when he stops to rest?

Speed of man towards West =2.5 m/s

Time to travel in the given direction = 1200 s

Total displacement towards west

Now speed of man towards East = 1 m/s

time to travel in east direction = 500 s

total displacement towards East

Now total displacement will be

so it is 2500 m towards west

prolly a beacuse the momentuem the car has increases while going down hill

the answer to this is proletariats.

hope this : )
