6. A 0.045 kg bullet is fired at 340 m/s at a 3.5 kg wooden block that is hanging from a 3 m long string. If the bullet passes through the block and emerges out the other side traveling at 50 m/s, what angle does
the string make with the vertical when the block gets to its highest position?

Two particles of masses m and 2m are placed on a smooth horizontal table. a string, which joins these two masses, hangs over the edge supporting a pulley, which suspends a particle of mass 3m.the pulley has negligible mass. the two parts of the string on the table are parallel and perpendicular to the edge of the table. the hanging parts of the string are vertical. find the acceleration of the particle of mass 3m.
