Equations of Kinematics

A particle starts its motion from rest under the action of a constant force. If the distance covered in first 10 seconds is S1 and that covered in the first 20 seconds is S2, then

Show answer and solution

Answer: (b)

  1. Constant force means constant aa; from rest S=12at2S = \frac{1}{2}at^2, so S∝t2S \propto t^2.
  2. S2S1=(2010)2=4\frac{S_2}{S_1} = \left(\frac{20}{10}\right)^2 = 4
  3. So the answer is (b) S2=4S1S_2 = 4S_1.
