41 kinetic friction free body diagram
This is my free body diagram to try and understand this: F net = 0 N m = 5 k g F F = 0.2 ( 42.4 N) = 8.48 N 24.5 + 8.5 = 33 N F N = ( 5 × 9.8) cos ( 30) Static friction = 0.2 ( 42.4) = 8.5 N 24.5 + 8.5 = 33 N x sin 90 = 33 sin 60 x = 38 N Answer is 43 N homework-and-exercises newtonian-mechanics forces friction free-body-diagram Share Draw a free body diagram (“fbd”) using the skills and definitions above. Solutions to the assigned problems. Class notes: Identifying the forces we will address, the directions they point and the formulas. Class notes: Creating free body diagrams, summing up the force equations from the diagrams. Some example problems. The free body diagrams for frames a-e show the existence of a new force which balances the force with which we push the crate. This force is called the static frictional fo . As we increase , rce s s f F F f also increases and the crate remains at rest. When reaches a certain limit the crate "breaks away" and accelerates...
