As you know
a=v-u/t
Speed = 126 km/h = 35m/s (Initial Velocity)
Distance = 200m
Final Velocity= 0 ( Comes to rest)
v=u+at, s=1/2atsquare + ut, v square = u square - 2as
a=v-u/t
Speed = 126 km/h = 35m/s (Initial Velocity)
Distance = 200m
Final Velocity= 0 ( Comes to rest)
v=u+at, s=1/2atsquare + ut, v square = u square - 2as
