As shown below, a bullet of mass m and speed v is fired at an initially stationary sphere. The bullet goes through the sphere, and exits with a speed of. The sphere is attached to a rigid pole of length L and negligible mass. What is the minimum value of v such that the sphere will barely swing through a complete vertical circle? (Use the following as necessary: m, L, g, and M for the mass of the sphere.) V = 12M√gl 5m m X Use conservation of energy to determine the speed of the sphere immediately after collision. Assume that at the top of the swing the sphere is momentarily at rest, so its kinetic energy is zero. Then apply conservation of momentum to find the initial minimum speed of the bullet.

Gravitational Slingshot Often in designing orbits for satellites, people use what is termed a "gravitational slingshot effect." The idea is as follows: A satellite of mass m; and speed v,i circles around a planet of mass m, that is moving with speed v in the opposite direction. See the diagram below: Although the satellite never touches the planet, this interaction can still be treated as a collision because of the gravitational interaction between the planet and satellite during the slingshot. Since gravity is a conservative force, the collision is elastic. Use an x-axis with positive pointing to the right. Solve for the unknowns below algebraically first, then use the following values for the parameters. m, = 2.40E+24 kg m; = 880 kg Viz = 3.050E+3 m/s Vpiz = -6.10E+3 m/s Solve for the final velocity of the satellite after the collision.
A 35 g steel ball is held by a ceiling-mounted electromagnet 3.4 m above the floor. A compressed-air cannon sits on the floor, 5.0 m to one side of the point directly under the ball. When a button is pressed, the ball drops and, simultaneously, the cannon fires a 25 g plastic ball. The two balls collide 1.2 m above the floor. What was the launch speed of the plastic ball?
Ballistic Pendulum To apply conservation of energy and momentum. As shown, an object of mass m is fired with an initial speed v0 at a ballistic pendulum’s bob. The bob has mass M and is suspended by a massless rod of length L. After the collision, the pendulum’s bob and object stick together and swing to a maximum angular displacement θ. Find an expression for v0, the initial speed of the object fired. Express your answer in terms of some or all of the variables m, M, L, and θ and g, the acceleration due to gravity.
2. A block of mass m=3 kg is sliding along a frictionless inclined surface that makes an angle of o = 30°with respect to the horizontal surface. At the lowest points of the inclined surface, a projectile is fired at a speed of v, = 12 m/s that makes an angle 8, = 45° with respect to the horizontal. Our aim of this problem is to find the time when the projectile will hit the block. e = 450 h = ? Ro= 10 m P= 30° x= ? (a) Find the time when the projectile hits the block. (Given, the initial distance between the block and the projectile along the inclined surface at t=0 is R, = 10 m as shown in the figure) Page 1 of 3 (b) Find the height h, where the projectile will hit the block. (c) Now assume that the projectile hits the block at its maximum range R along the inclined surface and the block is not sliding at all. Then find the maximum range along the inclined surface, Rmax = ?

1. Space probes may be separated from their launchers by exploding bolts. (They bolt away from one another.) Suppose a 4100-kg satellite uses this method to separate from the 1200-kg remains of its launcher, and that 3000 J of kinetic energy is supplied to the two parts. Assume that the satellite and launcher are at rest before separation and the direction of the satellite's velocity after separation is positive. Gravity is negligible compared to the force of explosion. Consider: Let the subscripts i and f denote the initial and final velocities and the subscripts s and/ denote the satellite and the launcher, respectively. How many knowns are there and how many unknowns? satellite launcher Before launch Vsf satellite launcher V₁ After launch
The mass of the concrete block shown in the figure is 5 kg and the spring stiffness is 25 kN/m. A bullet weighing 0.15 kg is fired at a speed of 500 m/s into the block when the system is at rest and ricochets back at a speed of 80 m/s (all in a horizontal trajectory). Assuming no shape change of the block and the bullet during collision.

Figure 2 shows a ballistic pendulum consists of 5 kg slender rod and 10 kg solid cylinder. The pendulum is originally at rest, θ = 0ᵒ. A 10 g bullet with velocity v is fired to the solid cylinder. c) However, it is observed that the cylinder swing upward to a maximum angle of θ = 22ᵒ. Determine the actual initial value of v. Then, analyze the linear impulse imparted by the bullet on the cylinder. Also, evaluate the force on the rod immediately just after theimpact.
