Two 2.4 kg balls are attached to the ends of a thin rod of negligible mass, 54 cm in length. The rod is free to rotate in a vertical plane about a horizontal axis through its center. With the rod initially horizontal as shown, a 0.33 kg wad of wet putty drops onto one of the balls with a speed of 3.7 m/sec and sticks to it.

1)What is the ratio of the magnitude of angular momentum of the entire system just after the collision to just before the collision? (|L|after/|L|before)

2)What is the angular speed of the system just after the putty wad hits?

3)What is the ratio of the kinetic energy of the entire system just after the collision to just before the collision? (KEafter/KEbefore)

4)Through what angle will the system rotate until it momentarily stops?

8%) Problem 15:   A rod of mass M = 3.5 kg and length L can rotate about a hinge at its left end and is initially at rest. A putty ball of mass m = 55 g, moving with speed v = 6.68 m/s, strikes the rod at angle θ = 59° from the normal at a distance D = 2/3 L, where L = 1.25 m, from the point of rotation and sticks to the rod after the collision....

A uniform thin rod of length 0.56 m and mass 3.2 kg can rotate in a horizontal plane about a vertical axis through its center. The rod is at rest when a 3.5 g bullet traveling in the rotation plane is fired into one end of the rod. As viewed from above, the bullet's path makes angle θ = 60° with the rod. If the bullet lodges in the rod and the angular velocity of the rod is 12.0 rad/s...

A uniform thin rod of length 0.45 m and mass 6.5 kg can rotate in a horizontal plane about a vertical axis through its center. The rod is a rest when a 3.0-g bullet traveling in the horizontal plane of the rod is fired into one end of the rod. As viewed from above, the direction of the bullet velocity makes an angle of 60° with the rod (see the figure). If the bullet lodges in the rod and the...
