A ball is attached to one end of a wire, the other end being fastened to the ceiling. The wire is held horizontal, and the ball is released from rest (see the drawing). It swings downward and strikes a block initially at rest on a horizontal frictionless surface. Air resistance is negligible, and the collision is elastic. The masses of the ball and block are, respectively, 1.7 kg and 2.3 kg, and the length of the wire is 1.12 m. Find the velocity (magnitude and direction) the ball (a) just before the collision, and (b) just after the collision.

4.12). As given in Figure 4, a thin uniform rod with mass M 3 kg and length I=0.4 m isfixed at one end and positioned horizontally. It swings after being released and collides with astationary block of mass m=1 kg at the lowest point of its swing. Then the block sticks to the lowerend of the rod and they keep swinging together until the rod makes an angle θ with the vertical. Findthe maximum value of θ that the rod block system can move up to. The moment of inertia of the rodabout its center is I rod=1/12mRod L^2

A student fires a 0.07 kg arrow at an object with mass m that is initially at rest on a frictionless surface. The speed of the arrow before the collision is 90 m/s.The speed when the arrow emerges from the object is v. What is the resulting velocity of the object?

A bullet of mass 0.0366kg and an initial speed of 353m/s is fired through a block of material with a thickness of 0.435m. The average force exerted on the bullet as it passes through the block has a magnitude of 1439N. What is the speed of the bullet, in meters per second, after passing through the block? The block is firmly fixed in place, so it does not move from its initial position
In a ballaistic pendulum, a bullet of mass m=5.50 g is fired with an initial speed vo=550 m/s at the bob of a pendulum. The bob has mass M=2.00kg and suspended by a rod of negligibel mass. After the collision, the bullet and bob stick together and swing through an arc, eventually gaining a height h. a) please find the h b) please find the kinetic energy of the system before the collison and after the collision (hint: use momentum conservation law for the collision process and then use energy conservation law for the swing process)
