Suppose you have a 120-kg wooden crate resting on a wood floor. (a) What maximum force can you exert horizontally on the crate without moving it? (b) If you continue to exert this force once the crate starts to slip, what will the magnitude of its acceleration then be?
Solution 4PE Step-by-step solution Step 1 of 3 (a) The maximum force that is necessary to start it top move is maximum statics friction. static friction coefficient The maximum force needed just before the crane starts to move is 588N Step 2 of 2 b) When the crate starts to move with 588N force, the kinetic friction exert in opposite direction. The kinetic friction is less than the static friction, because kinetic friction coefficient is smaller than statics friction coefficient. . The kinetic friction force on the crate.
