The feather took a time of t to fall from the top to the bottom of the tube. The diagram shows the experiment setup and the velocity-time graph of the feather as it falls. How far will the feather have fallen from the top of the tube in 0.5t ? A 0.13 L B 0.25 L C 0.50 L D 0.75 L 5 A uniform plank is pivoted at its mid-point. Two weights are added to the plank, one weight on each side of the pivot in the positions shown. A vertical force is applied at point X to balance the plank. What is the size and direction of this force? size/ N direction A 2.0 downwards B 2.0 upwards C 4.0 downwards D 4.0 upwards
