a level physics question. help!Watch this thread
The wooden block can swing freely at the end of a light inextensible string as shown in the
initial position of block
A pellet of mass 8.80 g strikes a stationary wooden block and is completely embedded in
it. The centre of mass of the block rises by 0.63 m. The wooden block has a mass of 450
(a) Determine the speed of the pellet when it strikes the wooden block.
i have been stuck on this for a while now
You have a similar system here. Just treat the block on the string as a pendulum. You should then be able to get the answer to part a).
