Homework Statement
In the given arrangement pulley P1 and P2 are moving with constant speed vo downward and the centre of the pulley P lies on the principal axis of a convex mirror having radius of curvature R. Find the speed of image of pulley P when it is at a distance x from the surface of convex mirror in terms of vo, R, x and θ
The Attempt at a Solution
This question is pretty easy but I got stuck at one point.
Using constraint relations,
I got 2vo - vcosθ + (L-xp)sinθ =0
where v is the velocity of Pulley P and L is the distance of the mirror from the upper fixed support.
i.e. v= (2vo + (L-xp)sinθ)/cosθ
This is not the final answer but as per the solution given v = 2vo/cosθ (which is written directly)
Can somebody explain me my mistake?
Thanks
