Equations of Kinematics

A body starts from rest, what is the ratio of the distance travelled by the body during the 4th and 3rd second?

Show answer and solution

Answer: (a)

  1. From rest, Sn=a2(2n−1)S_n = \frac{a}{2}(2n - 1).
  2. S4S3=2(4)−12(3)−1=75\frac{S_4}{S_3} = \frac{2(4) - 1}{2(3) - 1} = \frac{7}{5}
  3. So the answer is (a) 75\frac{7}{5}.
