Question: A 5 kg object is pushed with a force of 15 N. If the frictional force is 5 N, what is the acceleration of the object?

Options:

Correct Answer: 2 m/s²

Solution:

Net force = applied force - friction = 15 N - 5 N = 10 N. Acceleration = F/m = 10 N / 5 kg = 2 m/s².

A 5 kg object is pushed with a force of 15 N. If the frictional force is 5 N, what is the acceleration of the object?

A 5 kg object is pushed with a force of 15 N. If the frictional force is 5 N, what is the acceleration of the object?

Step 1: Identify the mass of the object. The mass is 5 kg.
Step 2: Identify the applied force. The applied force is 15 N.
Step 3: Identify the frictional force. The frictional force is 5 N.
Step 4: Calculate the net force by subtracting the frictional force from the applied force. Net force = 15 N - 5 N.
Step 5: Perform the subtraction. Net force = 10 N.
Step 6: Use the formula for acceleration, which is acceleration = net force / mass.
Step 7: Substitute the values into the formula. Acceleration = 10 N / 5 kg.
Step 8: Perform the division. Acceleration = 2 m/s².

Newton's Second Law of Motion – 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.
Net Force Calculation – Understanding how to calculate the net force by subtracting friction from the applied force.
Frictional Force – Recognizing the role of friction in opposing motion and how it affects the net force.
