Sample Problem and Solution Breakdown

To illustrate the effectiveness of Oxford Physics at Work 2 solutions, let's examine a typical problem and its step-by-step solution outline.

Problem Statement:

A car accelerates uniformly from a speed of 20 m/s to 30 m/s over a distance of 500 meters. Calculate the acceleration of the car and the time taken for this acceleration.

Step-by-Step Solution:

Step 1: Identify Known Values

• Initial velocity, \( u = 20\, \text{m/s} \)
• Final velocity, \( v = 30\, \text{m/s} \)
• Distance traveled, \( s = 500\, \text{m} \)

Step 2: Apply Kinematic Equation

Use the equation:

\[

v^2 = u^2 + 2as

\]

Solve for acceleration \( a \):

\[

a = \frac{v^2 - u^2}{2s}

\]

Step 3: Calculate Acceleration

\[

a = \frac{(30)^2 - (20)^2}{2 \times 500} = \frac{900 - 400}{1000} = \frac{500}{1000} = 0.5\, \text{m/s}^2

\]

Step 4: Calculate Time Taken

Use the equation:

\[

v = u + at

\]

Solve for \( t \):

\[

t = \frac{v - u}{a} = \frac{30 - 20}{0.5} = \frac{10}{0.5} = 20\, \text{seconds}

\]

Step 5: Summarize Results

• Acceleration: 0.5 m/s²

• Energy and Work: Conservation of energy, work-energy theorem.
• Electromagnetism: Fields, forces, and potentials.
• Thermodynamics: Heat transfer, efficiency calculations.
• Modern Physics: Quantum, nuclear phenomena within applied contexts.

Below, we analyze a representative problem, illustrating the solution process in detail.

Example Problem Breakdown: A Moving Car and Friction

Problem Statement (Hypothetical):

A car of mass 1200 kg accelerates from rest to a speed of 20 m/s over a distance of 500 meters. Assuming constant acceleration and that the only horizontal force doing work is kinetic friction with a coefficient of friction μ = 0.3, calculate:

1. The magnitude of the acceleration.
2. The work done by friction during the acceleration.
3. The power required at the moment the car reaches 20 m/s.

Step-by-Step Solution

Step 1: Identifying Known Data and Unknowns

Given:

• Mass, m = 1200 kg
• Initial velocity, u = 0 m/s
• Final velocity, v = 20 m/s
• Distance, s = 500 m
• Coefficient of kinetic friction, μ = 0.3

To find:

• Acceleration, a
• Work done by friction, W_friction
• Power at v = 20 m/s

Step 2: Calculating the Acceleration

Since the motion occurs over a known distance with initial and final velocities, use the kinematic equation:

v² = u² + 2as

Plugging in values:

(20)² = 0 + 2 a 500

400 = 1000a

a = 400 / 1000 = 0.4 m/s²

Result:

The car accelerates at 0.4 m/s².

Step 3: Determining the Force of Friction

Friction force:

F_friction = μ N

Since the surface is horizontal, the normal force N equals the weight:

N = m g = 1200 kg 9.8 m/s² = 11760 N

Thus,

F_friction = 0.3 11760 ≈ 3528 N

Step 4: Calculating the Work Done by Friction

Work done by friction (opposing motion):

W_friction = - F_friction s

W_friction = - 3528 N 500 m = - 1,764,000 Joules

The negative sign indicates that friction opposes the motion, removing energy from the system.

Step 5: Calculating the Work-Energy

Total work done on the car:

The initial kinetic energy:

KE_initial = 0 (since at rest)

The final kinetic energy:

KE_final = (1/2) m v² = 0.5 1200 400 = 240,000 Joules

Since work done by friction reduces the energy available, the work done by the engine (or driving force) must compensate for both the increase in kinetic energy and the work lost to friction:

Work_done_by_engine = KE_final - KE_initial + |W_friction|

Note that the work done by the engine must be positive enough to overcome friction and provide kinetic energy.

Step 6: Calculating Power at Final Velocity

Power is the rate at which work is done:

P = F_total v

Where F_total is the net force accelerating the car:

F_net = m a = 1200 kg 0.4 m/s² = 480 N

The engine must exert a force (F_engine) overcoming friction and providing acceleration:

F_engine = F_friction + F_net = 3528 N + 480 N = 4008 N

Power at the moment the car reaches 20 m/s:

P = F_engine v = 4008 N 20 m/s ≈ 80,160 Watts or approximately 80.2 kW

This is the instantaneous power required to sustain the acceleration at that moment.

Key Takeaways and Tips

• Always identify what is given and what needs to be found.
• Use diagrams to visualize the physical situation.
• Apply relevant physics principles systematically.
• Keep track of units and conversions.
