Homework Statement
* This is for my project.
The sled is placed at an inclined surface at an angle of theta. The sled is attatched to a rope, which i will be pulling to find out the minimum force to start the sled moving.
i would assume that when I am tryin to find the jusssttt jussst that point when it starts to move will i make Fnet = 0 ?
im finding out different amount of tensions needed to pull the skier up depending on the angles. i will be increasing the the angle by 15 degrees every interval. starting from 30 degrees.
--Im open to hear any opinions regarding my project, if you know that there is a way i could make it little bit more complex and interesting ? i will be very glad to hear them--
Homework Equations
Fnet = ma
The Attempt at a Solution
I know that when a mass of object is placed at an angle there is a
friction force, x-component of the gravity. These two forces appose the Tension force.
Ftension - Ffriction - Fgravityx = m a
would acceleration be 0 in this case?
so it would be Ftension = Ffriction +Fgravityx
but if it wants to move Ftension > Ffriction + Fgravityx right??
please HELP !
