Assuming Z is the length of the third line, you'd count the squares between each point to get the lengths, (3 at the top, 5 along the side), and then use Pythagoras' theorem. So, 3 squared + 5 squared = Z squared. 9 + 25 = 34, so your answer in radical form is √34. I hope this helps!
<span>E = 1/2 m v^2
v = sqrt(2*E/m)
= sqrt(2*4000/500)
= 4 m/s </span>
