In a shooting field where noone can get hurt, there is a
vertical square plastic board, 0.290 m on a side and with mass
0.730 kg , that rotates on a horizontal axis along its top edge.
The center of the plastic board is hit by a bullet with mass 1.60 g
that is moving with 380 m/s and that stays embedded in the plastic
board.
a)Find the angular velocity of the plastic board right after the
bullet's hit?
b)Calculate the maximum height above the equilibrium position does
the center of the plastic board reach before starting to go back
down again?
c)Find the minimum bullet velocity which would be required for the
plastic board to swing all the way over after impact?

Forensic scientists can determine the speed at which a rifle fires a bullet by shooting into a heavy block hanging by a wire. As the bullet embeds itself in the block, the block and embedded bullet swing up; the impact speed is determined from the maximum angle of the swing (a) Which would make the block swing higher, a 0.204 Ruger bullet of mass 2.14 g and muzzle speed 1290 m/s or a 7-mm Remington Magnum bullet of mass 9.71...

(5 pts) You shoot a bullet at a vertical target that is a uniform mass M and moment of inertia l (1/2)MR. The target is free to rotate without friction about the hanging point P that is at the edge of the target as shown. Bullet has mass m, very small radius comparing to the target and moment of inertia le. Bullet is spinning about the line of travel at...
