An 8.00 g bullet is fired into a 2.50 keg block that is initially at rest at the edge of a frictionless table of height 1.00 m (fig. P9.57). The bullet remains in the block, and after impact the block lands 2.00 m from the bottom of the table. Determine the initial speed of the bullet.
The system's initial velocity in the y direction (block plus bullet) is zero. only the acceleration brought on by gravity.
In y direction acceleration is zero.
This is initial velocity of system before falling down.
Now, apply conversation of momentum
Thus, speed of bullet m/s - Answer
