Question

under which condition is the magnitude of average velocity equal to average sped

Answer 1

if the displacement and distance is equal for equal interval of time then average velocity is equal to average acceleration.p provided they are moving in a straight line without any change in the direction.

we know that,
distance ≥ | displacement |

divide them by time,

distance/t ≥ | displacement |/t
average speed ≥ | average velocity |
