A bullet is fired with some velocity from bottom of a tall building, at the same time a wooden block is dropped from top of the building. The bullet gets embedded in the wooden block and the block moves up.
In this problem, can we apply conservation of linear momentum to find the velocity of the block after impact? Because net external is force acting on the bullet and block system.
I sovled this problem by applying CLM, and got the answer. But its nt convincing me.
