I have been studying this concept of slipping now it gets me pondered.. what if i have a crate on a truck and the truck is suppose to climb up a hill of 20 degrees. mass of crate is 100kg and coefficient of static friction and kinetic friction is 0.4 and 0.5 respectively. the question is: What...

Ok thanks! I got it now

Homework Statement Hi guys, i am sort of confused with the concept of slipping. I got a question.. what does it mean by maximum friction force before slipping occurs? Homework Equations I believe in the use of f_{}s \leq \mu_{}sn The Attempt at a Solution please correct me if i am wrong...

Homework Statement In the pulley-cable system shown, the acceleration of block A, x(double dot), varies with time, t(in seconds), as given by the expression x(double dot) = 2t m/s2. initially the two blocks are 5m apart and both are stationary...

please correct me if i am wrong here.. so i found the force acting on the left spring and right spring.. to find U, it means i have to sum the total work done by both springs? in this case, i should integrate FL and FR over the displacement right? but what should be limits of this...
