A conical pendulum is formed by attaching a ball of mass m to a string of length L, then allowing the ball to move in a horizontal circle of radius r. The following figure(Figure 1) shows that the string traces out the surface of a cone, hence the name.Part A: Find an expression for the tension T in the string.Express your answer in terms of the variables L,m,r and appropriate constants.Part B: Find an expression for the ball's angular speed?.Express your answer...
A stone with a mass of 0.700 kg is attached to one end of a string 0.800 m long. The string will break if its tension exceeds 50.0 N. The stone is whirled in a horizontal circle on a frictionless tabletop; the other end of the string remains fixed. A. Find the maximum speed the stone can attain without breaking the string.
A small block with a mass of 0.0600 kg is attached to a cord passing through a hole in a frictionless, horizontal surface (Figure 1). The block is originally revolving at a distance of 0.49 m from the hole with a speed of 0.77 m/s . The cord is then pulled from below, shortening the radius of the circle in which the block revolves to 9.0×10−2 m . At this new distance, the speed of the block is 4.19 m/s...
A small block on a frictionless horizontal surface has a mass of 0.0280 kg . It is attached to a massless cord passing through a hole in the surface. (See the figure below (Figure 1) .) The block is originally revolving at a distance of 0.310 m from the hole with an angular speed of 1.80 rad/s . The cord is then pulled from below, shortening the radius of the circle in which the block revolves to 0.115 m ....
