A uniform sphere made of modeling clay has radius R=0.34m and moment of inertia I=2.77 for rotation about a diameter. It is flattened to a disk with the same radius . What is the moment of inertia of the disk for rotation about an axis that is at the center of the disk and perpendicular to its flat surface?

Which of the following represents an upside-down image?

What is the average speed of a car that travels 40 mph for 1 hour and 60 mph in another hour?

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
