Question

e susJrom rest at the top of the well and falls for before hitting the water, how far does it fall? Moment of inertia of cylinder 1-% MR 2. A ladder is leant against the wall. The coefficient of the static friction p. between the ladder and the wall is 0.3 and the coefficient of the static friction g, between the ladder and the floor is 0.4. The center of mass of the ladder is in the middle of it Find the minimum angle that the ladder can form with the floor not to slip down. 3. A cookie jar is rolling up a 40.0° incline. At a point 0.50 m from the bottom of the incline (measured along the incline), it has a speed of 1.5 m/s a) What is initial speed of the jar? b) How much farther up the incline will the jar move? Consider the cookie bar as cylinder with moment of inertia 1-% MR A horizontal platform in the shape of a circular disk rotates on a frictionless bearing about a vertical axle through the center of the disk. The platform has a mass of 150 kg, a radius of 2.0 m, and a rotational inertia of 300 kgxm' about the axis of rotation. A 60-kg student walks slowly from the rim of the platform toward the center. 4. f the angular speed of the system is 1.5 rad's when the student starts at the rim, what is the angular speed when she is 0.50 m from the center?
