A ball of mass m is hang by a string of length l on a rough inclined plane with coefficient of friction μ and angle θ with the horizontal (μ=tanθ). Initially the ball is at the lowest position.
Calculate the minimum initial velocity, v, should be given to the ball to make a full circle of its path!

i solved it by putting tension = 0 at the top most point , i'll get velocity at the highest point and then applying work energy theorem. work done by tension and normal force will be zero . workdone by friction and gravity will come into picture .

I can't give much explanation here. It can be a spoiler.
Do you mind giving me your email, so I can explain to you by email?
