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 is rolling on a frictionless surface, shown in figure with a translational velocity v m//s . If is to climb the inclind surface then v should be :

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 sphere moving with a speed v_(0) on a smooth surface suddenly enters on a rough horizontal surface as shown. The angular momentum of the sphere about any point on the surface is conserved.

A solid sphere rolls on horizontal surface without slipping. What is the ratio of its rotational to translation kinetic energy.
