Answer 1

Answer #1

using conservation of momentum

m v r = ( ML^2/3 + m r^2) w

0.3* 12* 0.5 = ( 41* 1^2/ 3 + 0.3* 0.5^2) w

w = 0.131 rad/s

=======

b) option "no'' is correct

A door with mass M= 3.00 kg and width L=2.00m is hinged at one side so that it can rotate without friction about a vertical axis. A heavy bullet embeds in the 3L/4 of the door after it is fired as shown. The mass of the bullet is m=0.200kg and the initial speed of the bullet is speed 410 m/s . Part A Part complete What is the angular speed of the bullet and the door after the bullet embeds...
A 0.00600 kg bullet traveling horizontally with speed 1.00 103 m/s strikes a 20.8 kg door, embedding itself 11.0 cm from the side opposite the hinges. The 1.00 m wide door is free to swing on its frictionless hinges.

A 0.00600 kg bullet traveling horizontally with speed 1.00 103 m/s strikes a 20.8 kg door, embedding itself 11.0 cm from the side opposite the hinges as shown in the figure below. The 1.00 m wide door is free to swing on its frictionless hinges.What is the angular momentum? At what angular speed (rad/s) does the door swing open immediately after the collision?
