Block A has mass 1.00 kg and block B has mass 3.00 kg. The blocks collide and stick together on a level, frictionless surface.After the collision, the kinetic energy (KE) of block A is A: 1/9 the KE of block B B: 1/3 the KE of block B C: 3 times the KE of block B D: 9 times the KE of block B E: the same as the KE of block B

Add an output port block (Out block) to the simulation model, and this block can output the results to the MATLAB workspace.

Cylinder block or engine block is actually a complex machined casting unit.

block

manual block A: block controlled manually by a person known as a block operator. B: a fixed signal that lets engineers know if a train can enter a block.
