hmmm ... no, m increase as length increase

Since F=ma , if the force is constant and it is as stated in the problem, then there is constant acceleration and therefore changing velocity according to a=dv/dt

i asked myself the same thing, but that's what the question asks .. it beats me really

the height of a point at the tip of the chain off the ground is the length of the chain, the force is constant velocity will keep increasing yes

in this case y is the length, the question stated that initially it was at elevation of 0 so length will be 0, y max is the maximum length the chain will reach up the ground ... here is where my confusion start, I am not sure if the chain will stop going up at any point, so from this i...

Vf=Vi+at since Vi=0 >>> Vf=at ? or v=ds/dt KEi + PEi + Wext = KEf + PEf initially it was at rest v=0 and height was 0 that gives us Wext = KEf + PEf => W = 0.5mv^2+mghi don't have enough knowns to use this ...

Hey good people, I am new here and i found that you help people, i hope you can help me with this ive been triyng to solve this for a while but with no luck 1. Homework Statement A chain of mass m0 per unit length is loosely coiled on the floor. If one of the end is subjected to a constant...
