A a 20 gram bullet with an unknown velocity v is shot into a 5 kg wood block attached to a pivot with massless strings. What percentage of the original mechanical energy is left after the collision process? The remainder of the energy is converted into non-mechanical forms of energy such as thermal energy.

5. A bullet of mass m-0.02 kg was horizontally shot into a wood block of mass mo 8.98 kg, which is attached at one end of a spring with a spring constant k = 100 N/m, as shown in right Figure. After the bullet was embedded into the wood block, the spring was compressed 10 cm. If the coefficient of kinetic friction is 0.2 between the wood block and the surface, find the initial velocity of the bullet. (10 points)

A bullet of mass 8 g is fired into a 1.2 kg ballistic pendulum (a block of wood acting as the pendulum bob of a thin metal arm attached to a low friction pivot point) that is initially at rest. The bullet exits the block of wood with a speed of 180 m/s and the wooden block swings from its lowest point to a maximum height of 9.2 cm above that location. Determine the velocity of the bullet before it...

12. (20 points) A 5 gram bullet is fired at a wood block that is supported at rest on a smooth incline plane (no friction) at an angle of theta above the horizontal. The bullet is fired with a speed of 500 m/s, but then impacts and passes straight through the wood block, coming out the other side with a speed of 400 m/s. As a result of the collision, the wood block slides up the ramp 5 cm from...

A heavy bullet of mass m = 0.1200 kg is fired with an initial
velocity v = 400. m/s into a large block of lightweight wood of
mass M = 0.500 kg, which is initially at rest on a frictionless
surface. This initial situation is depicted on the left side of the
picture below. The bullet gets stuck inside of the wood block and
both move together thereafter as shown in the picture.

A target with mass m=3.5 kg is attached to a spring constant k=200 N/m on a horizontal, frictionless surface. The target is struck by a bullet with mass of 20 g, traveling at a speed of v=550 m/s. Bullet embeds itself completely into target. Assuming that the target is initally at rest, what is maximum displacement of the tagret fromthe spring equilbrium position after collision? Assume instant collision occurs. What percent of initial kinetic energy converted to non-mechanical forms of...

Ballistic and Springs-- An 8g bullet is shot into a 2.2-kg block of wood thatis initially at rest. The bullet embeds in the block, and together they slide on a horizontal frictionless surface at 1.2 m/s towards on unstrained ideal spring that is fixed to a wall. The spring is compressed by the block as it comes to a momentary stop. Ignore the effects of air resistance. (a) What is the velocity of the bullet immediately before it hits the...
