A ball rolls around a horizontal circle at height y inside the cone shown below. Find an
expression for the ball’s speed in terms of r(radius of cone),x(height of cone),p and g(9.81ms^-2).
r(radius of cone),x(height of cone),p and g(9.81ms^-2).
The Attempt at a Solution
i came across this question from a friend's tutorial but i stared at it whole day. cant think of any solutions,cant think of even where to start.
i tried using the variable g to form any possible relationship i could think of but the ball is moving in a horizontal circle..
