The problem involves a ballistic pendulum scenario where a bullet collides with a block, causing it to swing upward. Participants are tasked with finding the mass of the block based on the given parameters of the bullet's mass and velocity, as well as the height the block rises after the collision.
The discussion is ongoing, with participants exploring different aspects of the collision and energy transfer. Some guidance has been offered regarding the kinetic energy of the bullet and its implications for the block's motion, but no consensus has been reached on the correct approach to find the mass of the block.
Participants are working under the constraints of the problem statement, which does not provide explicit equations or methods for solving the mass of the block. There is an emphasis on understanding the energy transformations involved in the collision.

A 12g bullet is fired at 1600m/s into a wooden block of a ballistic pendulum, causing it to swing back, raising up 1.40m vertically. Find mass of the block
Homework Equations
N/a
The Attempt at a Solution
bullet momentum= 12g*1600m/s=19.2kgm/s
johndoe14 said:am i correct by saying that the block has a kinetic energy of____ due to the bullet
ke= .5*.012kg*1600m/s^2
= 15360kgm/s^2
