9) A bullet with mass 0.0075 kg is fired with a gun with mass 0.95 kg. The bullet leaves the gun at 380 m/s. a) What is the recoil speed of the gun? Assume the gun was at rest before firing. b) Is the momentum of the bullet greater, smaller or equal (in magnitude) to the recoil momentum of the gun? c) Find both the kinetic energy of the bullet and of the gun. Which is bigger, or are they equal? d) Thinking about your answers to (b) and (c) and about how dangerous the recoiling gun is compared to the fired bullet, reach a conclusion about which quantity (~p or K) is more relevant for the “damage” something can produce.

A bullet of mass 4.3 g is fired horizontally into a 7.4 kg wooden block at rest on a horizontal surface. The coefficient of kinetic friction between block and surface is 0.53. The bullet stops in the block, which slides straight ahead for 1.7 m (without rotation). (a) What is the speed of the block immediately after the bullet stops relative to it? (b) At what speed is the bullet fired?

A bullet with a mass of 4.1 g and a speed of 650 m/s is fired at a block of wood with a mass of 9.6x10-2 kg. The block rests on a frictionless surface and is thin enough that the bullet passes completely through it. Immediately after the bullet exits the block, the speed of the block is 21 m/s. a. What is the speed of the bullet when it exits the block? b. Is the final kinetic energy of...

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...

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.
