entify an example of how informal rules based on tradition play a part in American federalism. Multiple Choice All states have laws that require children to receive free education because Americans strongly believe in the value of education and the benefits of an educated population. The Second Amendment to the Constitution cites the need for a well-regulated militia, an American tradition that goes back to early colonial times. Local governments are responsible for primary and secondary education because schools have mostly been run directly by the most local governing bodies in America. The First Amendment to the Constitution protects the freedoms of speech and religion, which are deeply held values that go all the way back to the Enlightenment in the 1600s.

A bullet of mass 0.053 kg traveling horizontally at a speed of 200 m/s embeds itself in a block of mass 1.5 kg that is sitting at rest on a nearly frictionless surface. (a) What is the speed of the block after the bullet embeds itself in the block? v = ____ m/s (b) Calculate the kinetic energy of the bullet plus the block before the collision: $K_i$ = ____ J (c) Calculate the kinetic energy of the bullet plus the block after the collision: $K_f$ = ____ J d) Was this collision elastic or inelastic? \begin{itemize} \item elastic \item inelastic \item not enough information to tell \end{itemize} (e) Calculate the rise in thermal energy of the bullet plus block as a result of the collision: $\Delta E_{thermal, bullet} + \Delta E_{thermal, block}$ = ____ J (f) What was the transfer of energy Q (microscopic work) from the surroundings into the block+bullet system during the collision? (Remember that Q represents energy transfer due to a temperature difference between a system and its surroundings.) Q = ____ J
