Distance=100m = 0.1 km
Time=9.83 second= 0.0027 hours
Speed = Distance/time
speed= 0.1/0.0027
speed = 1/0.027
speed = 37.03 km/hr
Time=9.83 second= 0.0027 hours
Speed = Distance/time
speed= 0.1/0.0027
speed = 1/0.027
speed = 37.03 km/hr

using s=vt , v=s/t ....(1)
now, v = 100m/9.8sec = 0.1km /9.8 divided by 3600hr.
solving it comes to v= 36.734 ~ 37 km/hr
now, v = 100m/9.8sec = 0.1km /9.8 divided by 3600hr.
solving it comes to v= 36.734 ~ 37 km/hr
wrong
I got 36.73 using 9.8 value & not 9.836 . similarly if you put 9.863 value you'll get 36.62 as expected
