A sphere is rolling without slippin on a horizontal surface and velocity of its CM.w.r.t,the ground is v,What is linear velocity of :
the point Q highest point as shown in the fig.
.

A ball is thrown straight up. What is its velocity ad acceleration at the highest point?

A disc rotating about its axis with angular speed omega_0 is placed lightly (without any translational push) 011 a perfectly frictionless table. The radius of the disc is R. What are the linear velocities of the points A, B and C on the disc shown in Fig. 7.41? Will the disc roll in the direction indicated ?

A football is kicked into the air vertically upwards.What is its Velocity at the highest point.

A particle is thrown up vertically with a velocity of 50 m/s. What will be its velocity at the highest point of its journey?

What is the total kinetic eneryg of a solid sphere rolling on a surface and having translational velocity v?

A particle is thrown up vertically with a velocity of 50 m/s. What time would it take to reach the highest point?

Two small charged metal sphere A and B are situated in a vaccum. The distance between the centres of the spheres is 12.0 cm, as shown in the fig. The charge on each sphere may be assumed to be a point charge at the centre of the sphere. Point P is a movable point that lies on the line joining the centres of the sphere and is distance x fromt he centre of sphere A. The variation with distance x fo the electric field strength E at point P as shown in the figure. State the evidence provided by in the fig for the statement that the spheres are conductors, the charges on the spheres are either both positive or both negative.
