A block of mass m1 = 40 kg lies on a horizontal plane. The coefficient of kinetic
Fantastic news! We've Found the answer you've been seeking!
Question:
A block of mass m1 = 40 kg lies on a horizontal plane. The coefficient of kinetic friction of the plane block k = 0.3. The second block of mass m2 = 20 kg is placed on top of the first block. Determine the maximum force F (F parallel to the plane) on the first block, so that the second block remains above the first block. Coefficient of static friction of the first block and the second block S = 0.4
