I found out Vel. of bolt wrt lift =4(3)^1/2 m/s.
Now I used the formula of relative velocity as
Vel. Of bolt wrt lift + Vel.of lift wrt grd= Vel. Of bolt wrt grdie.
-4(3)^1/2 + 5 = 5+ 4(3)^1/2m/s
using this i got
vel. Of bolt wrt grd=5-4(3)^1/2 m/s which is different from the answer 5-10/(3)^1/2 m/s....so where am I wrong and why....plz help
