Physics is an extensive textbook that lays a solid foundation by introducing fundamental concepts such as precise measurements, mathematical tools, and the predictive power of physical laws. It methodically guides readers through classical mechanics—including one- and two-dimensional kinematics, forces, work, and energy—to more complex topics like rotational motion and simple harmonic motion. The book then expands into fluid dynamics, thermodynamics, wave phenomena, and the intricate behaviors of electric and magnetic fields, culminating in advanced subjects like special relativity, quantum mechanics, and nuclear physics. With a blend of theoretical explanations and real-world applications—from everyday phenomena to cutting-edge technology—the text provides a comprehensive framework for understanding the diverse and interconnected realms of physics.

Problem 1
The largest diamond ever found had a size of 3106 carats. One carat is equivalent to a mass of $0.200 \mathrm{~g}$. Use the fact that $1 \mathrm{~kg}(1000 \mathrm{~g})$ has a weight of $2.205 \mathrm{lb}$ under certain conditions, and determine the weight of this diamond in pounds.

Problem 2
A plane is sitting on a runway, awaiting takeoff. On an adjacent parallel runway, another plane lands and passes the stationary plane at a speed of $45 \mathrm{~m} / \mathrm{s}$. The arriving plane has a length of $36 \mathrm{~m}$. By looking out of a window (very narrow), a passenger on the stationary plane can see the moving plane. For how long a time is the moving plane visible?

Problem 3
A jetliner is moving at a speed of $245 \mathrm{~m} / \mathrm{s}$. The vertical component of the plane's velocity is $40.6 \mathrm{~m} / \mathrm{s}$. Determine the magnitude of the horizontal component of the plane's velocity.

Problem 5
A golfer, driving a golf ball off the tee, gives the ball a velocity of $+38 \mathrm{~m} / \mathrm{s}$. The mass of the ball is $0.045 \mathrm{~kg},$ and the duration of the impact with the golf club is $3.0 \times 10^{-3} \mathrm{~s}$. (a) What is the change in momentum of the ball? (b) Determine the average force applied to the ball by the club.
Problem 6
One average force $\overline{\vec{F}}_{1}$ has a magnitude that is three times as large as that of another average force $\overline{\mathrm{F}}_{2} .$ Both forces produce the same impulse. The average force $\overline{\mathrm{F}}_{1}$ acts for a time interval of $3.2 \mathrm{~ms}$. For what time interval does the average force $\overline{\mathrm{F}}_{2}$ act?
