a) True or False The marble is moving at constant speed on its way down the incline.

b) True or False The marble is moving at a constant speed when it is rolling on the horizontal surface.

c) True or False The average speed of the marble on the incline is less than the average speed of the marble on the horizontal part of the track.

d) True or False The instantaneous speed of the marble at the bottom of the incline is greater than the average speed of the marble on the incline.

A solid disk with a radius of 33.3 cm is moving so that its center of mass is initially moving at 4 m/s while also rolling without slipping at 12rad/s along a horizontal surface. It rolls up an incline, coming to rest as shown before rolling back down (drawing is not to scale). Consider the disk at the bottom of the hill. What is the ratio of the rotational kinetic energy to the total kinetic energy of the disk, Krot/Ktotal?A....

Two identical wheels are moving on horizontal surfaces. The center of mass of each has the same linear speed. However, one wheel is rolling, while the other is sliding on a frictionless surface without rolling. Each wheel then encounters an incline plane. One continues to roll up the incline, while the other continues to slide up. Eventually they come to a momentary halt, because the gravitational force slows them down. Each wheel is a disk of mass 3.73 kg. On...

A uniform marble rolls down a symmetric bowl, starting from rest at the top of the left side. The top of each side is a distance h above the bottom of the bowl. The left half of the bowl it rough enough to cause the marble to roll without slipping, but the right half has no friction because it is coated with oil. How far up the smooth side will the marble go, measured vertically from the bottom? How high...

A uniform solid marble, of mass m = 20.0 g and diameter 1.00 cm, rolls without sliding down a large symmetric steel bowl, starting from rest at point A, at the top of the left(no-slip) side. The top of each side is a distance h = 15.0 cm above the bottom of the bowl. The left half of the bowl is rough enough to cause the marble to roll without slipping, but the right half of the bowl is frictionless...
