As shown in the figure, a ball of mass m is connected to a string of length I to the top of a cone with frictionless sides. The cone is resting on the horizontal surface and the axis of the cone is vertical, making an angle of 30° with the side surface of the cone. The ball moves in a horizontal circle at a uniform speed v centered about the vertical axis of the cone. If the velocity v of the ball is greater than a certain velocity vo, it will lose contact with the surface of the cone and the angle o between the string and the vertical will no longer be 30°. 30! i. Prove that v, = Jgl sin 30° tan 30°. ii. Determine the tension T, in the string if the velocity of the ball is v = 3gl 2 (express you answer in terms of mg). Determine the angle p.

The W1= 69.01-lb block shown rests on a smooth plane (coefficient of kinetic friction = 0) with an angle of θ=34∘ from horizontal. It is connected by a flexible inextensible cord that passes around weightless, frictionless pulleys to a support. The W2 =134.93-lb weight is attached as shown. After the system is released from rest, in what distance will the block on the plain attain a speed of 10.0 ft/s?

The figure shows a schematic of a simple Watt governor mechanism with the spindle 0102 rotating at an angular velocity w about a vertical axis. The balls at P and S have equal mass. Assume that there is no friction anywhere and all other components are massless and rigid. The vertical distance between the horizontal plane of rotation of the balls and the pivot O₁ is denoted by h. The value of h = 400 mm at a certain w. If w is doubled, the value of h will be mm.
