Question: If a 2 kg object is pulled with a force of 10 N and experiences a frictional force of 4 N, what is its acceleration?

Options:

Correct Answer: 3 m/s²

Solution:

Net force = applied force - friction = 10 N - 4 N = 6 N. Acceleration a = F/m = 6 N / 2 kg = 3 m/s².

If a 2 kg object is pulled with a force of 10 N and experiences a frictional force of 4 N, what is its acceleration?

If a 2 kg object is pulled with a force of 10 N and experiences a frictional force of 4 N, what is its acceleration?

Step 1: Identify the mass of the object. The mass is 2 kg.
Step 2: Identify the applied force. The applied force is 10 N.
Step 3: Identify the frictional force. The frictional force is 4 N.
Step 4: Calculate the net force by subtracting the frictional force from the applied force: Net force = 10 N - 4 N.
Step 5: Perform the subtraction: 10 N - 4 N = 6 N. So, the net force is 6 N.
Step 6: Use the formula for acceleration, which is acceleration (a) = net force (F) / mass (m).
Step 7: Substitute the values into the formula: a = 6 N / 2 kg.
Step 8: Perform the division: 6 N / 2 kg = 3 m/s².
Step 9: Conclude that the acceleration of the object is 3 m/s².

Newton's Second Law – This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
Frictional Force – Understanding how friction opposes motion and affects the net force acting on an object.
Net Force Calculation – The process of determining the net force by subtracting friction from the applied force.
