A body covers 12m in 2nd second and 20m in 4th second. how much distance will it covers in 4th second after 5th second?
For a body doing the accelerated motion, it covers 12 meters between the 2nd and 1st second and 20 m between 4th and 3rd second. thus we are required to find the distance it covers between 9th and 8th second.
Let initial velocity be u and let acceleration be a.
