Potential Energy Function A single conservative force $F(x)$ acts on a $1.0 \mathrm{~kg}$ particle that moves along an $x$ axis. The potential energy $U(x)$ associated with $F(x)$ is given by $$ U(x)=(-4.00 \mathrm{~J} / \mathrm{m}) e^{(-x /(4.00 \mathrm{~m}))} $$ At $x=5.0 \mathrm{~m}$ the particle has a kinetic energy of $2.0 \mathrm{~J}$. (a) What is the mechanical energy of the system? (b) Make a plot of $U(x)$ as a function of $x$ for $0 \leq x \leq 10 \mathrm{~m}$, and on the same graph draw the line that represents the mechanical energy of the system. Use part (b) to determine (c) the least value of $x$ and (d) the greatest value of $x$ between which the particle can move. Use part (b) to determine (e) the maximum kinetic energy of the particle and (f) the value of $x$ at which it occurs. (g) Determine the equation for $F(x)$ as a function of $x$. (h) For what (finite) value of $x$ does $F(x)=0 ?$

A 80.0 -kg fireman slides down a $3.00-\mathrm{m}$ pole by applying a frictional force of $400 .$ N against the pole with his hands. If he slides from rest, how fast is he moving once he reaches the ground?

A $0.110 \mathrm{~kg}$ block of ice is placed against a horizontal, compressed spring mounted on a horizontal tabletop that is $1.30 \mathrm{~m}$ above the floor. The spring has force constant $2050 \mathrm{~N} / \mathrm{m}$ and is initially compressed $0.045 \mathrm{~m}$. The mass of the spring is negligible. The spring is released, and the block slides along the table, goes off the edge, and travels to the floor. If there is negligible friction between the block of ice and the tabletop, what is the speed of the block of ice when it reaches the floor?

INSTANT ANSWER

A car traveling at 20.9 m/s honks its horn as it directly approaches the side of a large building. The horn produces a long sustained note of frequency f0 = 217 Hz . The sound is reflected off the building back to the car's driver. The sound wave from the original note and that reflected off the building combine to create a beat frequency. What is the beat frequency that the driver hears (which tells him that he had better hit the brakes!)? Assume the speed of sound in air is 341 m/s.

A pendulum with a mass M swings and picks up a piece of clay of mass m at the bottom of its swing. Which of the following statements is correct? The combined mass rises to the same height that mass M was released. The total mechanical energy of the system is unchanged by the collision. If M = m, then the height it reaches after the collision is half that before the collision. If M = m, then the height it reaches after the collision is 1/4 that before the collision. If M = m, then it rises to twice the height it had before the collision.

Rebecca of mass 50 kg and Robert of mass 60 kg are initially at rest on a frictionless frozen lake. Robert throws a book of mass 0.50 kg at Rebecca with 20 m/s relative to the ice. Rebecca catches the book. Assuming the book is traveling horizontally, their final speeds are Multiple Choice VReb = 12.0 m/s, VRob = 17.0 m/s. VReb = 1.51 m/s, VRob = 4.17 m/s. VReb = 0.20 m/s, VRob = 0.17 m/s. VReb = 0.12 m/s, VRob = 6.17 m/s.
