A small disc A placed on a frictionless tabletop is connected to a small protrusion B on the tabletop with the help of an almost inextensible elastic cord of relaxed length l. There is a trap C in the table at distance n = 0.5 times of I from the protrusion. Initially the disc, the protrusion and the trap are in a line and the cord is straight and relaxed as shown in the top view of the setup. At what angle with the line AC must the disc be projected along the tabletop so that it enters the trap? Diameter of the protrusion is negligible as compared to the length of the thread.
Your professor has put 5 objects near the top of an inclined plane: a uniformdensity solid sphere, a hollow sphere, a hollow cylinder, a special solid cylinder in which the density is proportional to the radius (ρ(r) =αr), and a solid cube. The spheres and cylinders have radius R and will roll down the plane, while the cube has sides of length 2R and a frictionless coating,so it will slide down the plane. All objects are released at the same time. Which is the last to get to the bottom of the plane?   a) solid sphere b) hollow sphere c) hollow cylinder d) solid cylinder e) frictionless cube
A conical pendulum consists of a mass, m, at the end of a length of an ideal rope of length l that is moving in a horizontal circle (as shown in the figure below). The rope makes an angle with the vertical, defined as 8. The vertical angle is dependent on the length of the rope and the speed at which the mass moves. Assuming the mass is moving in uniform circular motion, calculate its speed, v, given that the length of the rope is = 5.50 m and the angle is 0= 70.5°. Take the acceleration l due to gravity as 9.81 m/s². V= O Search JY m/s DCE (2) 8:02 11/29/2
