Motion in A Straight Line question

2005 · Shift 0 · Q169

JEE MainPhysicsMotion in A Straight LineMCQ+4 / −1
A car starting from rest accelerates at the rate f through a distance S, then continues at constant speed for time t and then decelerates at the rate f2{f \over 2}2f​ to come to rest. If the total distance traversed is 15 S, then
  1. A
    S=16ft2S = {1 \over 6}f{t^2}S=61​ft2
  2. B
    S=ftS = ftS=ft
  3. C
    S=14ft2S = {1 \over 4}f{t^2}S=41​ft2
  4. D
    S=172ft2S = {1 \over 72}f{t^2}S=721​ft2
