Displacement = 0, assuming that he runs back to original position
Average velocity is displacement/ time, since displacement =0, velocity is also 0

a. Michael Johnson's displacement is 0 m

b. Michael Johnson's average velocity is 0 m/s

a. Michael Johnson's Displacement

Michael Johnson's displacement is 0 m

Since displacement, D = d' - d where

  • d = initial position and
  • d' = final position.

Let d = 0 m (Michael Johnson's starting point).

Since Michael Johnson runs one time round the track, his final position is his starting position. So, d' = 0 m

So, D = d' - d

D = 0 m - 0 m

D = 0 m

So, Michael Johnson's displacement is 0 m

b. Michael Johnson's average velocity

Michael Johnson's average velocity is 0 m/s

Average velocity, v = D/t where

  • D = total displacement and
  • t = total time

Given that Michael Johnson runs one time round the track of 400 m in 38 s, D = 0 m and t = 38 s

So, v = D/t

= 0/38

= 0 m/s

So, Michael Johnson's average velocity is 0 m/s
