# Two 500 g blocks of wood are 2.0 m apart on a frictionless table. A 10 g bullet is fired at 400m/s toward the blocks. It passes all the way through the first block, then embeds itself in the second block. The speed of the first block immediately afterward is 6.0m/s. What is the speed of the second block after the bullet stops?

Two 500 g blocks of wood are 2.0 m apart on a frictionless table. A 10 g bullet is fired at 400m/s toward the blocks. It passes all the way through the first block, then embeds itself in the second block. The speed of the first block immediately afterward is 6.0m/s. What is the speed of the second block after the bullet stops?

Step 1

Given:

Mass of each block = 500 g

Distance between them = 2 m

Mass of bullet = 10 g

Initial velocity of the bullet = 400 m/s

Initial velocity of the blocks = 0

Step 2

When bullet collide with 1st block

From the conservation of momentum

Step 3

When bullet collide with 2nd block

Form the...
