P is a set containing {-1,0,1,2}
x is a set which belongs to P. It can be said that x contains {-1,0,1,2}
So x^2 is a set containing { (-1)^2 , (0)^2 , (1)^2 , (2)^2 } => {0,1,4}
Q contains x^2 and x^2 contains {0,1,4}
Therefore, n(Q) = 3
Someone correct me if I'm wrong.

F=ma
ma 1= ma 2
2 * 2= 1 *a (since the mass of X is twice the mass of Y , so i've substituted 2 for mx and 1 for my)
a=2*2/1
a of Y is =4
so the should be D
hope this helps

The key concept for this question is Newton's 3rd Law: for each force, there must be an opposing force with the same magnitude.
Since X and Y are connected together by the spring, when the spring is pulling X to give it acceleration, X is also pulling the spring (the opposing force). And this opposing force is transferred onto Y.
Thus, Y is experiencing a force with equal magnitude to the force on X.
And according to Newton's 2nd Law, since Y's mass is half of X, it should have an acceleration 2 times of X.
