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

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
