kinematics

AIEEE 2015 Coaching › Mechanics questions › kinematics

a particle moving with uniform retardation covers three successive equal distance .the average velocity during the first and the third parts of the journey being 20m/s and 12m/s respectively .determine the average velocity in the middle part of the journey.

This is a good questino

the retardation is uniform..

so the time the first distance is travelled is such that

t₁.20=t₃.12
t₁.20=t₃.12

now with this hint, can you try and solve this?
