A 2 x 10^-3 kg bullet (m) is shot into a 5 kg block (M) of wood which is fixed to a friction less horizontal surface. The bullet hits the block at v = 500m/s 1) Calculate the magnitude of the momentum of the bullet as it hits the block. 2) The bullet embeds itself in the block. How much work is done by the resistive force due to the block in bringing the bullet to rest? 3) The average...

The same constant force, F, is applied to two blocks. The first
block has a mass of M and the second block has a mass of 2M. Both
blocks are initially at rest and the force acts on each of them for
the same period of time, t.
15) After time, t, which block has
more momentum?
a)The block of mass M
b)The block of mass 2M
c)They will have the same momentum

True and False 1. If two particles of different masses have equal kinetic energy they also have equal momentum. 2. If the momentum of a single particle is zero, its kinetic energy may not be zero. 3. The kinetic energy is always conserved both in elastic collisions and inelastic collisions. 4. A large force always produces a larger impulse on a body than a smaller force. 5. If the kinetic energy of a single particle is zero, its momentum must...

Forensic scientists can determine the speed at which a rifle fires a bullet by shooting into a heavy block hanging by a wire. As the bullet embeds itself in the block, the block and embedded bullet swing up; the impact speed is determined from the maximum angle of the swing (a) Which would make the block swing higher, a 0.204 Ruger bullet of mass 2.14 g and muzzle speed 1290 m/s or a 7-mm Remington Magnum bullet of mass 9.71...

and final values. Does own (and hence can be solved Guided Problem 5.4 Burrowing bullet A gun that has a muzzle velocity of 600 m/s is used to fire a 12.0-g bullet horizontally into a 4.00-kg block of wood initially at rest. The bullet passes completely through the block, with negligible loss of inertia to either object. After the collision, the block slides at 1.20 m/s in the direction of the bullet's motion. What is the change in internal energy...

OAL Combine the concepts of conservation of energy and conservation of momentum in inelastic collisions. In figure a, a bullet and a wooden block are shown in two configurations. In the first configuration, the block, labeled m2, hangs vertically from a ceiling. A bullet, labeled m1, approaches the block horizontally from the left. A rightward arrow points from the bullet and is labeled vector v1i. A rightward arrow, shorter than the first, points from the block and is labeled vector...
