Q)
(chatquestion)...A small block A of mass 1 kg is placed on a long block B of mass 4 kg, another block C
of mass 2 kg is approaching the block B with a velocity 10 m/s, collides the block B. the
coefficient of restitution of the collision is e
coefficient of friction between the
blocks A, B is =05and no friction at all the other contacts. The final velocity of the
block A will be :
30
m/s
