A projectile of mass m moves to the right with a speed vi
(Fig. P11.50a). The projectile strikes and sticks to the end of a
stationary rod of mass M, of length d, that is pivoted about a
frictionless axle through its center (Fig. P11.50b).
a) Find the angular speed of the system right after the
collision. (Use vi, m, M, and d as appropriate in your
equation.)
(b) Determine the fractional loss in mechanical energy due to
the collision....

A system of two bodies consisting of a rod of mass m and length L, and a disk of mass M and radius R, moves in the x-y plane. The disk rotates about the axis attached to the rod at a distance b from its axis of rotation. The absolute angular velocity of the rod is 2, and the angular velocity of the disk relative to the rod is @. Determine the ratio E/Ho of the kinetic energy E of...

1. A thin rod of mass M and length d hangs vertically from a frictionless pivot attached to one end. A piece of clay of mass m moving horizontally at a speed v hits the rod a distance x from the pivot and sticks to it. Discussion Questions: (In the first 5-10 min a random group will be selected to explain.) • What “type” of collision is happening? What is and is not conserved? • Consider the analogous linear momentum...

A blob of putty of mass m moves with a speed 2v to the right, while a second blob of putty of the same mass m moves with a speed v to the left, as shown. Their paths are separated by a distance b. They both reach a thin rigid rod of length b and mass 2m at the same instant t-0, and stick to opposite ends of the rod. (Use standard definitions of a right- handed coordinate system with...

1. A wooden rod of length 40.0 cm and mass 1.00 kg is sitting on a frictionless horizontal surface. The rod has a pin through its centre so that it can freely rotate about a vertical axis perpendicular to the rod and passing through the center of the rod. A projectile of mass 0.0100 kg is now shot at the rod. The projectile is moving horizontally with a speed of 2.00 x 102 m/s in the direction perpendicular to the...

Mass m = 0,1 kg moves to the right with speed v = 0.39 m/s and collides with an equal mass initially at rest. After this inelastic collision the system retains a fraction = 0.63 of its original kinetic energy. What is the speed VR (in m/s) of the mass which was originally at rest before the collision?

Mass m = 0.1 kg moves to the right with speed v = 0.57 m/s and collides with an equal mass initially at rest. After this inelastic collision the system retains a fraction = 0.75 of its original kinetic energy. How much impulse (in units of N sec) does the mass originally at rest receive during the collision?
