A 25 kg object is pulled with a force of 100 N. If the frictional force is 25 N, what is the acceleration of the object? (2023)

Correct Answer: 3 m/s²

Step 1: Identify the total force applied to the object, which is 100 N.
Step 2: Identify the frictional force acting against the motion, which is 25 N.
Step 3: Calculate the net force by subtracting the frictional force from the total force: 100 N - 25 N = 75 N.
Step 4: Identify the mass of the object, which is 25 kg.
Step 5: Use the formula for acceleration, which is acceleration = net force / mass.
Step 6: Substitute the values into the formula: acceleration = 75 N / 25 kg.
Step 7: Calculate the acceleration: 75 N / 25 kg = 3 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.
Frictional Force – Frictional force opposes the motion of an object and must be subtracted from the applied force to find the net force.
Net Force Calculation – The net force is calculated by subtracting the frictional force from the applied force.
