A sphere rolls on a horizontal surface. Is there any point of the sphere which has a vertical velocity?

A solid sphere is rolling on a horizontal surface such that speed of the centre of sphere is u. Mase of the sphere is m and radius R. Magnitude of angular momentum about the point of contact is found to be (7)/(n)mvR /. Find the value of n

A solid sphere rolling on a rough horizontal surface with a linear speed v collides elastically with a fixed, smooth, vertical wall. Find the speed of the sphere after it has started pure rolling in the backward direction.

A solid sphere spinning about a horizontal axis with an angular velocity omega is placed on a horizontal surface. Subsequently it rolls without slipping with an angular velocity of :

A hollow sphere rolls without slipping the on the horizontal surface such that its translational velocity is v . Find that the maximum height attained by it on an inclined surface.

A solid sphere of mass m and radius r is rolling on a horizontal surface. What ratio of total energy of the sphere is: Kinetic energy of rotation ? Kinetic energy of translation ?

A wheel is rolling without slipping on a horizontal surface. In an inertial frame of reference in which the surface is at rest, is the reanypoint on the wheel that has a velocity that is purely vertical ? Is there any point that has a horizontal velocity component opposite to the velocity of the centre of mass ? Explain. What would be the results if wheel is slipping with rolling ?

A sphere rolling on a rough horizontal surface with constant velocity then it start going up on a smooth inclined plane. Rotational KE of sphere decreases continuosly on horizontal and inclined surface. Rotational KE decreases if torque due to friction opposes angular velocity of sphere.

A solid sphere rolling on a rough horizontl surface with a lilner speed v collides elastically with a fixed, smooth, vertical wall. Find the speed of the sphere after it has started pure rolling in the backward direction.

A solid sphere rolling on a rough horizontl surface with a lilner speed v collides elastically with a fixed, smooth, vertical wall. Find the speed of the sphere after it has started pure rolling in the backward direction.

A uniform solid sphere rolls on a horizontal surface with a linear speed of 10 m/s. It then rolls up a.plane inclined at 30° to horizontal. What is the height upto wlrich the sphere rises ? (See Fig.) Assume that the surface is frictionless. Also calculate the distance travelled by the Fig. sphere on the inclined plane ?
