same retarding force so same acceleration x = Vi t - (1/2) a t^2 v = Vi - a t so for final v = 0 t = Vi/a x = Vi^2/a - (1/2)Vi^2/a = Vi^2/a if Vi new =2 Vi then x = 4 Vi^2/a 4 times as far

Sajjad Mehmood · Answer

x = Vi t - (1/2) a t^2 when we put t=a/2 it will be you changed the whole equation x = Vi x 2/a - (1/2)a x (2/a)^2
