fig 4E.43 shows two discs kept on a smooth horizonal surface . Disc 1 is projected towards disc 2 with velocity `vecv_(0)` After collculate the magnitude of outgoing velocitites of disc, 1 and disc 2.

A disc of mass m and radius R is kept on a smooth horizontal surface with its plane parallel to the surface. A particle of same mass m travelling with speed v_(0) collides with the stationery disc and gets embedded into it as shown in the figure. Then

A small disc and a thin uniform rod of length l, whose mass is eta times greater than the mass of the disc, lie on a smooth horizontal plane. The disc is set in motion, in horiozontal direction and perpendicular to the rod, with velocity v, after which it elastically collides with the end of the rod. Find the velocity of the disc and the angular velocity of the rod after the collision. At what value of eta will the velocity of the disc after the collision be equal to zero? reverse its direction?

Three identical discs A, B, and C (figure) rest on a smooth horizontal plane. The disc A is set in motion with vector v after which it experiences an elastic collision simultaneously with the discs B and C. The distance between the centres of the latter discs prior of the collision is eta times greater than the diameter of each disc. Find the velocity of the disc A after the collision. At what value of eta will the disc A recoil after the collision, stop, move on?

A uniform disc of radius r_(0) lies on a smooth horizontal plane. A similar disc spinning with the angular velocity omega_(0) is carefully lowered onto the first disc. How soon do both discs spin with the same angular-velocity if the friction coefficient between them is equal to mu ?

A uniform disc of mass m and radius R is released gentiy on a horizontal rough surface. Such that centre of the disc has velocity V_(0) towards right and angular velocity omega_(0) (anticlockwise) as shown. Disc will certainly come back to its intial position if

A uniform solid disc of mass 1 kg and radius 1m is kept on a rough horizontal surface. Two forces of magnitude 2N and 4N have been applied on the disc as shown in the figure. Linear acceleration of the center of mass of the disc is if there is no slipping is
