Challenge Problems
Push your limits with challenges.
Question 1
A block of mass 5 kg is resting on a horizontal surface. Calculate the normal force acting on the block. If the surface has a friction coefficient of 0.3, what is the maximum static friction force?
💡 Hint: Use the weight of the block to find normal force first.
Question 2
If an object is being pulled with a force of 100 N and opposes with friction of 60 N, what is the acceleration of the object with mass 10 kg?
💡 Hint: Determine net force first then apply Newton's second law!
