Question 1

Which of the following best describes the primary focus of PHYS 1061, Elementary Classical Physics I, at Temple University?

Accepted Answer

It is a calculus-based course focusing on classical mechanics, including motion, energy, and Newtonian dynamics.

Question 2

A student throws a ball straight up with an initial velocity of $$v_0 = 10$$\ \mathrm{m/s}$$. Neglecting air resistance, what is the maximum height reached by the ball? (Use g = 9.8$$\ \mathrm{$$m/s^2$$}$$)

Accepted Answer

$$h_{max} = \frac{v_0$^2}{2g} = \frac{100}{19.6} \approx 5.1\ \mathrm{m}$$

Question 3

Which of the following is NOT a topic covered in PHYS 1061 according to the syllabus?

Accepted Answer

Electricity and magnetism

Question 4

A car accelerates uniformly from rest to a speed of $$20\ \mathrm{m/s} in$$ $$10\ \mathrm{s}. $$What is the acceleration of the car?

Accepted Answer

$$a = \frac{v_f - v_i}{t} = \frac{20 - 0}{10} = 2\ \mathrm{m/s^2$}$$

Question 5

Accepted Answer

Plagiarism is defined as the unacknowledged use of another person's work, ideas, words, or assistance.

Question 6

A block of mass $$m$$ slides down a frictionless incline of height $$h. $$What is its speed at the bottom?

Accepted Answer

$$v = \sqrt{2gh}$$

Question 7

Question 8

A $$2\ \mathrm{kg}$$ object moving at $$3\ \mathrm{m/s}$$ collides elastically with a stationary $$1\ \mathrm{kg}$$ object. What is the velocity of the $$2\ \mathrm{kg}$$ object after the collision?

Accepted Answer

$$v_1$$' = \frac{$$m_1$$ - $$m_2$$}{$$m_1$$ + $$m_2$$} $$v_1$$ = \frac{2 - 1}{2 + 1} 	imes 3 = 1\ \mathrm{m/s}$$

Question 9

Accepted Answer

Practice problems regularly and use the textbook as a primary learning resource.

Question 10

A rotating disk has a moment of inertia $$I$$ and angular velocity $$\omega. $$What is its rotational kinetic energy?

Accepted Answer

$$K = \frac{1}{2} I \$$omega^2$$

Question 11

Which of the following is a prerequisite for enrolling in PHYS 1061?

Accepted Answer

A strong background in algebra and trigonometry

Question 12

A $$5\ \mathrm{kg}$$ object is acted on by a net force of $$20\ \mathrm{N}. $$What is its acceleration?

Accepted Answer

$$a = \frac{F}{m} = \frac{20}{5} = 4\ \mathrm{m/s^2$}$$

Question 13

Which of the following is NOT allowed during quizzes and exams in PHYS 1061?

Accepted Answer

Using your own handwritten notes

Question 14

A $$0.2\ \mathrm{kg}$$ ball is attached to a $$0.5\ \mathrm{m}$$ string and swung in a horizontal circle at a constant speed of $$2\ \mathrm{m/s}. $$What is the tension in the string?

Accepted Answer

$$T = m \frac{v^2$}{r} = 0.2 	imes \frac{4}{0.5} = 1.6\ \mathrm{N}$$

Question 15

Which of the following best describes the homework policy for PHYS 1061?

Accepted Answer

No late homework will be accepted for any reason.

Question 16

A $$3\ \mathrm{kg}$$ object moving at $$4\ \mathrm{m/s}$$ collides inelastically with a $$2\ \mathrm{kg}$$ object at rest. What is their final velocity after the collision?

Accepted Answer

$$v_f = \frac{m_1$ v_1$ + m_2$ v_2$}{m_1$ + m_2$} = \frac{3 	imes 4 + 2 	imes 0}{3 + 2} = 2.4\ \mathrm{m/s}$$

Question 17

Which of the following is a real-world application of the conservation of angular momentum?

Accepted Answer

A figure skater spinning faster by pulling in their arms

Question 18

A $$10\ \mathrm{kg}$$ box is pulled across a horizontal surface with a force of $$50\ \mathrm{N} at an $$angle of $$30^\circ$$ above the horizontal. If the coefficient of kinetic friction is $$0.2$$, what is the acceleration of the box? (Use $$g = 9.8\ \mathrm{m/s^2$})$$

Accepted Answer

$$a = \frac{F \cos 	heta - \mu_k m g}{m} = \frac{50 	imes 0.866 - 0.2 	imes 10 	imes 9.8}{10} = \frac{43.3 - 19.6}{10} = 2.37\ \mathrm{m/s^2$}$$

Question 19

Which of the following is a fundamental law covered in PHYS 1061?

Accepted Answer

Newton's Second Law: $$F = ma$$
