Question

A bullet of mass 4.00 g travelling at 250 m/s embeds into a wooden block of mass 2.32 kg resting on a horizontal surface. The coefficient of kinetic friction between block and surface is 0.220. The bullet remains embedded in the block slides along the surface before stopping. What distance does the block slide before coming to rest?

Answer #1

A bullet of mass 4.00 gg is fired horizontally into a wooden
block of mass 1.14 kgkg resting on a horizontal surface. The
coefficient of kinetic friction between block and surface is 0.170.
The bullet remains embedded in the block, which is observed to
slide a distance 0.270 mm along the surface before stopping.
Part A
What was the initial speed of the bullet?

A bullet of mass 6.00 g is fired horizontally into a wooden
block of mass 1.29 kg resting on a horizontal surface. The
coefficient of kinetic friction between block and surface is 0.210.
The bullet remains embedded in the block, which is observed to
slide a distance 0.290 m along the surface before stopping.
What was the initial speed of the bullet?

A 5.50 g bullet is fired horizontally into a 1.40 kg wooden
block resting on a horizontal surface. The coefficient of kinetic
friction between block and surface is 0.200. The bullet remains
embedded in the block, which is observed to slide 0.230 m along the
surface before stopping. Find the initial speed of the bullet.

A bullet of mass 1.4×10−3 kg embeds itself in a wooden block
with mass 0.987 kg , which then compresses a spring (k = 130 N/m )
by a distance 5.5×10−2 m before coming to rest. The coefficient of
kinetic friction between the block and table is 0.46.

b)What fraction of the bullet's initial kinetic energy is
dissipated (in damage to the wooden block, rising temperature,
etc.) in the collision between the...

wood table? Assume that ?k=0.20.

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...

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 0.0200 kg bullet moving horizontally at 400 m/s embeds itself
into an initially stationary 0.500 kg block.
(a) What is their velocity just after the collision? m/s
(b) The bullet-embedded block slides 8.0 m on a horizontal
surface with a 0.30 kinetic coefficient of friction. Now what is
its velocity? m/s
(c) The bullet-embedded block now strikes and sticks to a
stationary 2.00 kg block. How far does this combination travel
before stopping? m
