Is the answer ~15.36m/s or 10.26m/s?
If yes then here’s how I did-
=>v2=v02+as (2xs/2=s)
=>v2=as …................................(A)
Now v becomes v0 for the second case,
=>182=v2+as
=>324=2as
=>as=162
=>v2=162
v=12.72
Now average speed, v (conjugate)= u+v/2=30.72/2=15.36
I don’t remember very well, but the average speed could also be=u+v+vf/3=30.72/3=10.26m/s
