Question

1. You shoot a bullet of mass m=0.025 kg into a wood box of mass M=1.7 kg which initially is at rest. After the impact, the wood with embedded bullet moves to the flat top of the hill, and it continues its motion on the top. Initial speed of the bullet before collision is vo=560 m/s. The height of the hill is h=0.3 m. The surface has no friction. At what speed the wooden block moves on the top of the hill?

Answer #1

a bullet of mass m=5g is fired into a wooden block with mass M=
0.995 kg which then compresses a spring (k=100N/m by a distance of
x=0.1 before coming to rest. the bullet remains embedded in the
wooden block. ignore friction between the block and table. a) what
is initial speed of the bullet? b) calculate total kinetic energy
of the bullet block-system immediately before and after the
collision. is the collision between the bullet and the block
elastic or...

An 0.025 kg bullet traveling at 700 m/s strikes and passes
through the center of mass of a 0.50 kg block of wood that is
initially at rest on a smooth flat surface. The bullet passes
through the block and emerges from the other side traveling at 300
m/s? How fast will the block be sliding just after the bullet
emerges, and how much energy (in Joules) will be converted to heat?
(Neglect the effect of sliding friction during the...

A bullet of mass ma= 0.01 kg moving with an initial
speed of va= 200 m/s embeds itself in a wooden block
with mass mb= 0.99 kg moving in the same direction with
an initial speed vb= 2.6 m/s. What is the speed of the
bullet-embedded block after the collision? What is the total
kinetic energy of the bullet and block system before and after the
collision?

A bullet of mass m is fired into a block of mass M that is at
rest. The block, with the bullet embedded, slides distance d across
a horizontal surface. The coefficient of kinetic friction is
?k.
What is the speed of a 9.0 g bullet that, when fired into a 8.0
kg stationary wood block, causes the block to slide 5.6 cm across a
wood table? Assume that ?k=0.20.

A wood block of Mass M=3.00 kg and rests horizontally at the
bottom of a ramp. A bullet of mass m=0.0420kg with an intial
velocity v0 is fired at the wood block and embedded inside the
block. The wood blocl and the embedded bullet together move up the
ramp and reach a vertical heigh of yf= 2.40m relative to the bottom
of the rmap(yo=0) before sliding downward. Ignore friction/air
resistance.
a) What is the total mechanical energy of the block+bullets...

13. A 10.0-g bullet is fired into a stationary block of wood
(m = 5.00 kg) at the speed of 300 m/s, the
relative motion of the bullet stops inside the block. Determine the
speed of the bullet-plus-wood combination immediately after the
collision.

A bullet of mass m is fired into a block of mass
M that is at rest. The block, with the bullet embedded,
slides distance d across a horizontal surface. The
coefficient of kinetic friction is μk
A) What is the speed of a 12 g bullet that, when fired into a
9.0 kg stationary wood block, causes the block to slide 5.6 cm
across a wood table? Assume that μk=0.20
Express your answer to two significant figures and
include...

A bullet is fired toward a block of wood (m1 = 1.17
kg) sitting on a frictionless surface. The bullet has a mass
mb = 30 g, and its initial velocity is 320 m/s in the
+x-direction. The bullet embeds itself inside the block of wood.
Then the block of wood (with bullet) collides with another block of
wood (m2 = 1.20 kg). The collision is elastic. The first
block moves off at an angle of -45o with respect to...

A bullet with mass m1 = 3.00 g is fired into a wooden block of
mass m2 = 1.00 kg, that hangs like a pendulum. The bullet is
embedded in the block (complete inelastic collision). The block
(with the bullet embedded in it) goes h = 30.0 cm high after
collision. Calculate the speed of the bullet before it hit the
block.

A 10 g bullet is fired into a 9.0 kg wood block that is at rest
on a wood table. The block, with the bullet embedded, slides 5.0 cm
across the table. The coefficient of kinetic friction for wood
sliding on wood is 0.20. What was the speed of the bullet?
