The theory of special relativity explains the connection between space and time to objects that move in a straight line at a constant speed. The objects move at the speed of light. When an object approaches light speed, its mass is endless and cannot move faster than light. The most crucial postulate of Einstein's special relativity is that the laws of nature do not change in each frame of reference.

Question

Two blocks of masses 8 kg and 8.9 kg are
placed on a horizontal, frictionless surface. A

Squids and octopuses propel themselvesby expelling water. They do this by keeping water in a cavity andthen suddenly contracting the cavity to force out the water through anopening. A 6.50 kg squid (including the water in the cavity) at rest suddenlysees a dangerous predator. (a) If the squid has 1.75 kg of water inits cavity, at what speed must it expel this water suddenly to achieve aspeed of 2.50 m/s to escape the predator? Ignore any drag effects of thesurrounding water. (b) How much kinetic energy does the squid createby this maneuver?
