Question
What is the frictional force if a 200 N force pulls a 50 kg block producing an acceleration of 3.0 m/s²?
Correct Answer
Option A is the correct answer.
Detailed Explanation
Net force = ma = 50 × 3 = 150 N. Friction = applied force − net force = 200 − 150 = 50 N.
Hint
Applied force must overcome friction and provide acceleration.
