I can write the equation towards the center : T + mg cos0 = mv^2/R
and I consider the energy at the moment of escape and the highest position
I get the equation (0.5)mv^2 = (0.5)m(vcos0)^2 + mgy
then I try to diff. the above equation of y respect to the angle 0
it is right?
A mass is attached to one end of the massless string, the other and of which is attached to a foxed support. The mass swings around in a vertical circle as shown in Fig 5.36. Assuming that the mass has the minimum speed necessary at the top of the circle to keep the string from going slack, at...
A bead, under the influence of gravity, slides along a frictionless wire whose height is given by the function y(x), Assume that at position 9x,y) = (0,0), the wire is horizontal and the bead passes this point with a given speed v to the right. What should the shape of the wire be(that is, what...
