Solution

## The correct option is C with an initial velocity and moves with uniform accelerationThe distance covered in nth second isSn=u+12(2n−1)awhere u is initial velocity & a is accelerationthen, 26=u+19a2.........(1)28=u+21a2..........(2)30=u+23a2..........(3)32=u+25a2............(4)From eqs.(1)and (2) we get u=7m/s, a=2m/s2∴ The body starts with initial velocity u=7m/s and moves with uniform acceleration a=2m/s2
