Homework Answers
(a) As the bullet remains in the block, we can treat it as an inelastic collision.
Let 1 represent bullet and 2 represent block
m1v1 + m2v2 = (m1 + m2)v
as block was at rest initially, so we have
m1v1 = (m1 + m2)v
v = m1v1 / m1 + m2
v = 0.015 * 50 / 0.015 + 2.5
v = 0.2982 m/s
-----------------------------------------------------------------------------
Initial energy = 1/2 * m1 * v12 = 1/2 * 0.015 * 502 = 18.75 J
final energy = 1/2 * (m1 + m2) * v2 = 0.1118 J
so,
energy dissipated = 18.75 - 0.1118
energy dissipated = 18.638 J

2) A 10.0-g bullet is fired into, and embeds itself in, a 1.80-kg block attached to a spring with a force constant of 22.4 N/m and whose mass is negligible. How far is the spring compressed if the bullet has a speed of 300 m/s just before it strikes the block and the block slides on a frictionless surface? Note: You must use conservation of momentum in this problem because of the inelastic collision between the bullet and block. ___...

A heavy bullet of mass m = 0.1200 kg is fired with an initial
velocity v = 400. m/s into a large block of lightweight wood of
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.
