Um for the example I think the statement is still true... I think it is saying
For all x: (x < some Natural Number y -> there exists some y < x)
And since this is true for all x then that statement is true for that example, and is not a counter example... I think.
Though those domains and...
Hey guys,
I've been given a problem and I attempted it but I have no idea if it is right, I was hoping you guys could help me.
Show that (∀x)(∃y)(p(x, y) -> p(y, x)) is a tautology.
Since, I am new to logic and Predicate Calculus I was wondering if someone could check my working, (I was...
Thanks for your quick reply OlderDan! I think I know what you are saying... Is the following correct?
So is this calculation correct:
from
R=\frac{v^2sin2\theta}g
v=\sqrt{\frac{Rg}{sin2\theta}}
so v = (200*9.8/sin50)^(1/2)
v = 50.582 m/s
J=P_f - P_i = m(v_f - v_i)
so
J =...

Hi,
I've been going through some past exam papers for the physics paper I'm doing (I got my exam tomorrow), and I came across this question:
A golf ball of mass 46 g is struck a blow by a club such that the impulse imparted to the ball...
