Question

Shown below is a small particle of mass 33 g that is moving at a speed of 10 m/s when it collides with and sticks to the edge of a uniform solid cylinder. The cylinder is free to rotate about the axis through its center and perpendicular to the page. The cylinder has a mass of 0.4 kg and a radius of 16 cm and is initially at rest.

A) What is the angular velocity (in rad/s) of the system after the collision?

B) How much kinetic energy (in J) is lost in the collision?

Answer #1

Shown below is a small particle of mass 21 g that is moving at a
speed of 10 m/s when it collides with and sticks to the edge of a
uniform solid cylinder. The cylinder is free to rotate about the
axis through its center and perpendicular to the page. The cylinder
has a mass of 0.7 kg and a radius of 20 cm and is initially at
rest.

A small object with a mass of 1.62 kg is moving with a speed of
290 m/s (with respect to the ground) when it collides with a rod
with a mass of 11.99 kg and a length of L m. The rod is
initially at rest, in a vertical position, and pivots about an axis
going through its center of mass which is located exactly halfway
along the rod. The object imbeds itself in the rod at a distance
L/4...

A 200-g particle moving at 5.0 m/s on a frictionless horizontal
surface collides with a 300-g particle initially at rest. After the
collision the 300-g object has a velocity of 2.0 m/s at 45o below
the direction of motion of the incoming particle. What is the
velocity of the incoming particle after the collision? What
percentage of the initial kinetic energy is lost in the
collision?

A 10 g bullet is fired at 394.5 m/s into a solid cylinder of
mass 22.1 kg and a radius 0.57 m. The cylinder is initially at rest
and is mounted on fixed vertical axis that runs through it's center
of mass. The line of motion of the bullet is perpendicular to the
axle and at a distance 8.3 cm from the center. What is the initial
angular momentum of the system?
