Answer:
2.0 kg
Explanation:
For a closed system, the momentum is always conserved. Momentum of an object is given by mv where m is the mass and v is the velocity.
Momentum of the system before the collision is given by:
<h3>p1 + p2 = 1.2*1.2 + x*4.4 (where x is the mass of the 2nd block);</h3>
Momentum of the system after the collision is given by:
Mv where M is the combined mass of the 2 blocks as they stick together and v is the velocity.
<h3>Momentum = (1.2+x)*3.2</h3>
As the momentum is conserved i.e momentum before collision and after collision is the same:
<h3>(1.2+x)*3.2 = 1.2*1.2 + 4.4*x</h3><h3>Evaluate x to get the mass of the 2nd block.</h3>
It seems that you have missed the necessary options for us to answer this question, but anyway here are the answers. The interaction between two optical and perceptual phenomena makes moving pictures possible. the persistence of vision provides the illusion of SUCCESSION <span>while the phi phenomenon provides the illusion of MOVEMENT. Hope this helps.</span>
