A solid sphere rolls in released from rest and rolls down an incline plane, which is 2.0 m long and inclined at a 30° angle from the horizontal. (a) Find its speed at the bottom of the incline. (Remember that the kinetic energy in rolling motion is the translational kinetic energy ½ Mv2 of the center, plus the rotational K.E. ½ Iω2 about the center. Also remember that v = ωr if the sphere rolls without slipping.) (b) Find the...
A disk of m=5 kg and radius r=2 m starts from rest and rolls down a 20 degree incline from an initial height of 50 m. What is the linear velocity of the disk as it reaches the bottom of the incline? What is the rotational kinetic energy of the disk at the halfway point between the positions 1 and 2? If it takes 1.2 seconds for the disk to reach the bottom of the incline, find the magnitude of...

9. From top of an incline plane with height of 80.0 cm a cylinder with radius of 20.0 cm and mass of 5.0 kg is released. The cylinder is rolling down and reaches to end of the plane. The inclination angle of plane is 30 degrees. Find speed of cylinder at end of the plane. Plane is frictionless. Moment of inertia for ring is I= MR2. (use conservation of energy using rolling kinetic energy) 10. Find center of gravity...
