Time taken to cover second metre
Distance traveled=1m
Acceleration=0.25m/s^2
Using,s=ut+1/2at^2
1=1/2*1/4*t^2
1=1/8*t^2
t=2√2
So,time taken to cover last 1m=4-2√2=1.7s

Answered by Sagnik
The ans is wrong becoz it will 1.17 second and not 1.7 seconds
Answered by Xyz
First find the time that needs to cover 1m distance and then from that find the final velocity at the end of 1m. Then with distance formula s=ut+1/2at^2 find the time.

YES , THE VALUE OF t = 2 root 2 = 2.82 seconds !
