A 4 . 00 g bullet is moving horizontally with a velocity of 355 m / s to the right. The bullet is approaching two blocks resting on a horizontal frictionless table of height 25 . 0 c m above the ground. Air resistance is negligible. The mass of the first block is 1150 g , and its velocity is 0 . 550 m / s after the bullet passes through it. The mass of the second block is 1530 g . If the bullet passes completely through the first block and embeds itself in the second one, as indicated in Fig. 4.1, (a) what is the velocity of the second block after the bullet embeds itself and (b) what is the ratio of the total kinetic energy of the bullet-blocks system after the collision to the one before the collision? If the bullet passes completely through both blocks and moves with a velocity 50 . 0 m / s after leaving the second block, as indicated in Fig. 4.2, (c) what is the velocity of the second block after the collision? After the bullet leaves the two blocks, the first block collides with the second block and moves with a velocity 0 . 200 m / s after the collision (see Fig. 4.2), (d) what is the velocity of the second block after the collision with the first block? The second block eventually leaves the table and falls to the ground, (e) what is the speed of the second block right before it hits the ground? phys1401_final_fig4.jpg
