no.41 Fsmax-98.4 11. You are pushing a 2.3-kg crate across the floor with a force of 9.5 N. If the coefficient of kinetic frictio between the crate and the floor is 0.32, what is the frictional force between the crate and the floor? Justify your answer. 12. An experiment was performed where a 123-N block resting on a horizontal table was pulled by a string with an increasing amount of force. The figure shows a graph of the frictional force exerted on the block v the horizontal force pulling on the block. ƒ(N) z (a) According to the graph, what in the maximum static friction between the block and the table? 75N 75.0 50.0 A
