Question

a car starting from rest and moving with uniform accelaration on
a straight road travels for sometime such that the paths described
by it in the last second and the penultimate seconds of the motion
are in the ratio 4/3 respectively calculate the total time
travelled by the body

Let t is total time of the journet
as initial body was at rest u = 0distance travelled in last secondst = u + a22t-1st = 0+a22t-1distance travelled in penultimate second st-1 = a22(t-1)-1stst-1 = 2t-12t-343 = 2t-12t-3t = 4
