What is the difference between atoms and particals? Help

Otrada [13]

An atom is the smallest unit of matter that forms a chemical element. An atom is made up of three kinds of subatomic particles: electrons, protons, and neutrons.A molecule is a combination of atoms bonded together through a covalent bond. Generally, we think of molecules as having no charge (although molecular ions do exist)

A 11 gram bullet is fired horizontally into a 100g wooden block that is initially at rest on a frictionless horizontal surface a

oksian1 [2.3K]

Answer:

The speed of the bullet at impact equals 57.44 m/s

Explanation:

Since the surface is friction less thus no energy shall be lost in the system

Equating the initial kinetic energy of the bullet with the final potential energy of the compressed spring we get

$E_{i}=\frac{1}{2}mv^{2}$

Potential Energy of the compressed spring is given as

$E_{f}=\frac{1}{2}k(\delta x)^{2}$

given

k = 120 N/m

m = 11 grams

x = 55 cm

Equating the 2 energies and solving for velocity we get

$\frac{1}{2}mv^{2}=\frac{1}{2}k(\delta x)^{2}\\\\v^{2}=\frac{k(\delta x)^{2}}{m}\\\\v^{2}=\frac{120\times (0.55)^{2}}{11\times 10^{-3}}\\\\v^{2}=3300\\\\\therefore v=57.44m/s$
