Question

a particle covers half of its total distance with speed v1 and the rest half distance with speed v2. its average speed during the complete journey is​

Answer 1

Answer:

v₁v₂/2

Explanation:

t₁=(S/2)/v₁

  =S/2v₁

t₂=S/2v₂

avg.speed=S/t₁+t₂

v=S / (S/2v₁)+(S/2v₂)

 =S / [S/2(1/v₁+1/v₂)]

S gets canceled

=v₁v₂/2

hope it helped and pls mark as brainliest:)
