A playground merry-go-round of radius R = 2.2C m has a moment of inertia I = 265 kg middot m^2 and is rotating at 8.0 rev/min about a frictionless vertical axle. Facing the axle, a 23.0-kg child hops onto the merry-go-round and manages to sit down on the edge. What is the new angular speed of the merry-go-round?
The fiqure below shows a solid cube with a mass m on an inclined plane, at angle e above horizontal. R The cube is attached at one end to a spring with spring constant k at one end and a lightweight string at the other. The string is in turn wound around a reel with a radius R and moment of inertia I. The axle of the reel and the incline both have negligible friction The reel is turned counterclockwise...

Facing the axle, a 24.0-kg child hops onto the merry-go-round and manages to sit down on the edge. What is the new angular speed of the merry-go-round
A playground merry-go-round of radius R = 1.80 m has a moment of inertia I = 245 kg · m2 and is rotating at 12.0 rev/min about a frictionless vertical axle. Facing the axle, a 23.0-kg child hops onto the merry-go-round and manages to sit down on the edge. What is the new angular speed of the merry-go-round? rev/min
An m = 13.6 kg mass is attached to a cord that is wrapped around a wheel of radius r = 11.3 cm (see the figure below). The acceleration of the mass down the frictionless incline is measured to be a = 1.98 m/s2. Assuming the axle of the wheel to be frictionless, and the angle to be theta= 33.0o determine the tension in the rope. Determine the moment of inertia of the wheel. Determine angular speed of the wheel...
You pull on a string with a horizontal force F = 34 N that is attached to a block of mass mb = 7.1 kg, then to the axle of a solid cylinder of mass mc = 5.7 kg and radius r = 0.4 m, then to a spring of spring constant k = 115 N/m. This is all done on an inclined plane where there is friction ( Us = 0.6 and k = 0.30 ), and the incline...
A solid, frictionless cylinder reel of mass M= 2.95 kg and radius R = 0.392 m is used to draw water from a well (see Figure (a)). A bucket of mass m= 1.82 kg is attached to a cord that is wrapped around the cylinder. (Indicate the direction with the sign of your answer.)(a) Find the tension T in the cord and acceleration a of the bucket. T = ??? N a = ?? m/s2 (b) If the bucket starts from...
A playground merry-go-round of radius R = 2.10 m has a moment of inertia of I = 260 kgm2 and is rotating at 11.0 rev/min about a frictionless vertical axis. Facing the axle, a 23.0 kg child hops on to the merry-go-round and manages to sit down on its edge. What is the new angular speed of the merry-go-round?
A cylindrical fishing reel has a moment of inertia of I = 6.01E-4 kg*m2 and a radius of 4.46 cm. A friction clutch in the reel exerts a restraining torque of 1.18 N*m if a fish pulls on the line. The fisherman gets a bite, and the reel begins to spin with an angular acceleration of 60.1 rad/s2. What is the force of the fish on the line?

The pulley shown (Figure 1) has a moment of inertia IA = 0.625 kg⋅m2 , a radius r = 0.250 m , and a mass of 20.0 kg. A cylinder is attached to a cord that is wrapped around the pulley. Neglecting bearing friction and the cord’s mass, express the pulley’s final angular velocity in terms of the magnitude of the cord’s tension, T (measured in N), 4.00 s after the system is released from rest. Use the principle of...
