Question

the tension in the rod and boxes, (c) How would the answers to (a) and (b) change if the uncles trailed the aunts? Figure 6-58 Problem 37. A 40 kg slab rests on a frictionless floor. A 10 kg block rests on top of the slab (Fig. 6-58). The coefficient of static friction mustat between the block and the slab is 0.60, whereas their kinetic friction coefficient mukin is 0.40. The 10 kg block is pulled by a horizontal force with a magnitude of 100 N What are the resulting accelerations of (a) the block and (b) the slab? A locomotive accelerates a 25-car train along a level track. Every car has a mass of 5.0 times 104 kg and is subject to a

Explanation / Answer

so lets do the block first the block will feel two forces in the x direction F- friction = ma and two in the y N - mg = 0 so friction = uN = u mg so 100-u mg = ma 100 - 0.4*10*9.81=10a so a=6.1 m/s^2 now for the slab it only feels the friction force we know from part a that friciton = 0.4*10*9.81 so 0.4*10*9.81=40a a=0.98
