Answer:
67.8 m.
Explanation:
For 0.3 sec which is the response time , he will keep on moving with velocity
undiminished or at 26 m/s .
Distance travelled during this period
= 26 x .3 =7.8 m
For rest of the time ie during 4 - .3 = 3.7 s , he decelerates with deceleration of 5.3 ms⁻² and initial velocity of 26 m/s
s = u t - 1/2 a t²
s = 26 x 3.7 - .5 x 5.3 x 3.7 x 3.7
= 96.2 - 36.28
= 60 m approx.
Total distance travelled
=60 + 7.8 = 67.8 m.
