In the attached figure, block A of mass 2.0kg slides on a horizontal frictionless table with velocity of 3.0m/s and collides with block B of mass 3.0kg initially at rest on the edge of the table. Block B moves with a horizontal velocity of 2.4m/s, just after the collision.
(a) Use conversation of momentum to find the velocity of Block A, after the collision
(b) Is the collision elastic? (Hint: Verify K.E. of the block before & after collision)
(c) What is the kinetic energy of block B, just before it strikes the floor 0.40m below the table's surface? (Hint use conservation of M.E.)
