Question

(numbers 12-14) A 4 kg block is stacked on top of a 6 kg block which initially slides to the right on a horizontal floor. The 4 kg block does not slide on the 6 kg block (they move together as one unit). The coefficient of kinetic friction between the 6 kg block and the floor is 0.2.

(numbers 12-14) A 4 kg block is stacked on top of a 6 kg block which initially slides to the right on a horizontal floor. The 4 kg block does not slide on the 6 kg block (they move together as one unit). The coefficient of kinetic friction between the 6 kg block and the floor is 0.2. 12. Find the magnitude of the horizontal force that the 4 kg block exerts on the 6 kg block. sli ding 4 N c) 8 N d) 12 N e) 16 N and points to the 13. The horizontal force that the 4 kg block exerts on the 6 kg block is a) static friction, left b)static friction, right c) kinetic friction, left d) kinetic friction, right e) more info is needed to determine

Explanation / Answer

12) here horizontal force is frictional force

f = mue*mg

f = 0.2*4*10 = 0.2*40 = 8 N

13) static friction provides the necessary force to wads the horizontal direction through right side.
