A block of mass “m” sits on a (bigger) block of mass “4m” that is on a frictionless table. The coefficients of friction between the two blocks are μs (static) and μk (kinetic). Assume that a horizontal force “F” is applied to the block on top (i.e. the smaller block with mass “m”). The force “F” is variable. The figure below is representative of this scenario. (You may use m = 10 kg, μs = 0.8, μk = 0.6, and...
A block of mass m = 2.0 kg is sitting stationary on a table. A horizontal force of magnitude F = 5.0 N is applied to the block, as shown. The coefficient of static friction is µS = 0.7, and the coefficient of kinetic friction is µK = 0.5.
