In the classic illustration of a bullet hiting a block suspended by a string, BR notes that the length of the string makes no difference on the change in height the bullet climbs.
How does this make sense?
If a string is only 3cm long, the block can only climb 6cm at the most (assuming circular path).
But if the string is a 5cm long, the same bullet can cause the block to rise maybe 10cm.
So... BR is wrong? Right?
I dont see any 2 ways around this.
Change in the L string length obviously seems to change height bullet climbs.
