A billiard ball moving with a speed of `5 m//s` collides with an identical ball, originally at rest. If the first ball stop dead after collision, then the second ball will move forward with a speed of:

A ball moving with speed u collides with an identical ball at rest. The velocities of two balls after collision are (If the collision is elastic):

A ball of mass m, moving with a speed 2v_0 collides inelastically (e>0) with an identical ball at rest. Show that for head-on collision, both the balls move forward.

A ball of mass m , moving with a speed 2v_(0) collides inelastically ( e gt 0) with an identical ball at rest . Show that (a) For head - on collision , both the balls move forward . (b) For a general collision , the angle between the two velocities of scattered balls is less than 90^(@)

A ball of mass m m , moving with a speed 2upsilon_(0) , collides inelasticaly (egt0) with an identical ball at rest. Show that (a) For head - on collision, both the balls move forward. (b) For a genergcollision, the angle between the two velocities of scattered balls is less that 90^(@) .

A ball of mass m m , moving with a speed 2upsilon_(0) , collides inelasticaly (egt0) with an identical ball at rest. Show that (a) For head - on collision, both the balls move forward. (b) For a genergcollision, the angle between the two velocities of scattered balls is less that 90^(@) .

A heavy ball moving with speed v collides with a tiny ball. The collision is elastic, then immediately after the impact, the second ball will move with a speed approximately equal to
