A 4.00g bullet is moving horizontally with a velocity of +355 m/s, where the + sign indicates that it is moving to the right (see part a of the drawing). The bullet is approaching two blocks resting on a horizontal frictionless surface. Air resistance is negligible. The bullet passes completely through the first block (an inelastic collision) and embeds itself in the second one, as indicated in part b. Note that both blocks are moving after the collision with the...

A bullet shot from a small firearm has an initial velocity v0 of 52 m/s at an angle theta = 42 with respect to the horizontal. At the maximum trajectory (max height), we observe that, the bullet explodes into two small pieces both of which are of equal mass. One fragment  immediately after the explosion is therefore zero m/s and it falls vertically. How long (in seconds) does it take the shell to reach this point trajectory (max height)? What is...
