A bullet of mass m = 8.00 g is fired into a block of mass M...
A bullet of mass m = 8.00 g is fired into a block of
mass M = 220 g that is initially at rest at the edge of a
table of height h = 1.00 m (see figure below). The bullet
remains in the block, and after the impact the block lands
d = 2.10 m from the bottom of the table. Determine the
initial speed of the bullet.

A bullet of mass m = 8.00 g is fired into a block of
mass M = 210 g that is initially at rest at the edge of a
table of height h = 1.00 m (see figure below). The bullet
remains in the block, and after the impact the block lands
d = 1.90 m from the bottom of the table.
Determine the initial speed of the bullet.

A bullet of mass m = 29 g is fired into a wooden block of mass M
= 4.9 kg as shown in the figure below. The block is attached to a
string of length 1.5 m. The bullet is embedded in the block,
causing the block to then swing as shown in the figure. If the
block reaches a maximum height of h = 0.27 m, what was the initial
speed of the bullet?

1. A bullet of mass m=5 g moving with an initial velocity v_0,
is shot into pendulum bob of mass M=25g. The pendulum bob is
suspended by a light rod of length L=1.2 m.
What is the minimum velocity of the bullet so that the system
after the collision barely swings through a complete vertical
circle?
a) Assume an inelastic collision
b) Assume a perfect elastic collision

A bullet with a mass m b = 11.5 g is fired into a block of wood
at velocity v b = 265 m/s. The block is attached to a spring that
has a spring constant k of 205 N/m. The block and bullet continue
to move, compressing the spring by 35.0 cm before the whole system
momentarily comes to a stop. Assuming that the surface on which the
block is resting is frictionless, determine the mass of the wooden...
