Question
As shown below, a block of mass 2.00 kg is placed on top of a larger block of mass 14.0 kg, and the two-block system rests on a horizontal surface. There is friction between the two blocks, as well as between the larger block and the surface, with static and kinetic friction coefficients of mu s = 0.300 and mu k = 0.200, respectively. As shown below, a horizontal force F is applied to the larger block. Use g = 10 m/s2, and try doing this problem without a calculator. If the blocks are initially at rest, what is the minimum value of the horizontal force F necessary to start the system moving? Once the blocks are moving, what is the minimum value of the horizontal force F necessary to keep the system moving at constant velocity? Once the blocks are moving, what is the maximum value the horizontal force F can be such that the small block does not slide on the large block?Explanation / Answer
A) 48 N
B)32 N
C) 48 N
