The diagram depicts a laboratory experiment in which a feather is released from rest inside a long evacuated vertical tube with length $L$. The feather takes time $T$ to travel from the top of the tube to the bottom. How far below the top of the tube will the feather have travelled in time $0.50T$?
- A$0.13L$
- B$0.25L$
- C$0.38L$
- D$0.50L$
