Homework Statement
1 Kg block slides on a circular rod (no friction) from rest in A position by a force of 40N. What is the speed when it reached point B. (see attached pic)
Homework Equations
W(f)=E(B)-E(A)
The Attempt at a Solution
The energy in A is 0, the energy in B is mgh+0.5mv^2
My problem is how to find the work of the force.
Thx.
