Sample Questions and Solutions for the AP Physics Unit 3 Practice Test
In preparation for the AP Physics Unit 3 exam, it is crucial to practice with sample questions to ensure a thorough understanding of the material. The following questions and solutions provide a valuable resource for students looking to improve their problem-solving skills and solidify their knowledge of the unit.
Question 1:
- Two objects, A and B, with masses of 2 kg and 4 kg, respectively, are connected by a massless string that passes over a frictionless pulley. Object A is on a rough horizontal surface with a coefficient of kinetic friction of 0.2. Object B is hanging vertically. What is the acceleration of the system?
Solution 1:
To solve this problem, we need to determine the net force acting on the system. Since the pulley is massless and frictionless, the tension in the string is the same on both sides.
First, let’s analyze the forces acting on object A. There is a tension force acting to the right, and a friction force acting to the left. The friction force can be calculated using the equation:
Friction force = coefficient of friction x normal force
where the normal force is equal to the weight of object A:
Normal force = mass of object A x gravity
Since the object is on a rough surface, the friction force opposes the motion, so it acts to the left. The net force on object A is the difference between the tension force and the friction force:
Net force on A = tension force – friction force
The net force on object B is the tension force minus the weight:
Net force on B = tension force – weight of object B
Since the system is connected, the tension force is the same for both objects. Equating the net forces for objects A and B, we can solve for the acceleration:
Net force on A = (mass of object A x acceleration) – (coefficient of friction x normal force)
Net force on B = (mass of object B x acceleration) – weight of object B
Setting the net forces equal to each other:
(mass of object A x acceleration) – (coefficient of friction x normal force) = (mass of object B x acceleration) – weight of object B
Solving for acceleration:
acceleration = ((coefficient of friction x normal force) + weight of object B) / (mass of object A + mass of object B)
Substituting the values:
acceleration = ((0.2 x (2 kg x 9.8 m/s²)) + (4 kg x 9.8 m/s²)) / (2 kg + 4 kg) = 3.27 m/s²
Therefore, the acceleration of the system is 3.27 m/s².
Question 2:
- An object with a mass of 2 kg is attached to a spring with a spring constant of 100 N/m. The object is stretched 0.1 m from its equilibrium position and released. What is the period of oscillation?
Solution 2:
The period of oscillation for a mass-spring system can be calculated using the equation:
Period = 2π * √(m/k)
Where m is the mass of the object and k is the spring constant.
Substituting the values into the equation:
Period = 2π * √(2 kg / 100 N/m) = 2π * √(0.02 s²) ≈ 0.89 s
Therefore, the period of oscillation is approximately 0.89 seconds.
