Question
Our topic is STATIC AND KINETIC FRICTION. Give a detailed explanation and clear image for the solution. I add formula together with the problem if it can make it a lot easier for you to answer it but if its not related to the problem, kindly disregard it. Thank you.
Transcribed Image Text:1. A skier is standing motionless on a horizontal patch of snow. She is holding
onto a horizontal tow rope, which is about to pull her forward (see Figure below).
The skier's mass is 59 kg, and the coefficient of static friction between the skis
and snow is 0.14.
(a) Draw the free-body diagram of the skier
(b) What is the magnitude of the maximum force that the tow rope can apply to
the skier without causing her to move?
Transcribed Image Text:Static friction fs is the force acting on an object when FA (applied force) is less than or
equal to the product of µs (coefficient of static friction) and FN (normal force).
fs < µsFN (magnitude of static friction)
FMAX
(the equality holds true when fs is at maximum)
When you try to push a heavy load and it did not move then your applied force is so
small that the static friction cancels its effect. But the time that you strongly applied a
force on the heavy load, the kinetic friction fk took place right after fs reaches its
таxiтum.
fk = HKFN
(magnitude of static friction)
