What is q1?
Show answer
A 1010 kg box on a level floor has μk=0.25\mu_k = 0.25. Calculate the kinetic friction force while it slides (g=9.8g = 9.8 m/s squared). [2 points]
What is q2?
Show answer
A box needs 4040 N to start moving but the applied force is only 3030 N. State the static friction force. [1 point]
