- Homework Statement
- A large rope having linear mass density is being pulled by a horizontal force so that lower portion of rope is at rest and upper portion is moving with constant velocity v as shown in figure. The value of F, is

- Relevant Equations
- F = dp/dt

F= dmv/dt

dm = lamda dx [ lamda = linear mass density ]

dx/dt = velocity

[ p = momentum] p = mv

So i got some equations but i think i am missing something, my main doubt is what is the relation between dx / dt and v(o) [ here] . Workings in attachment
