hey here is one i am kinda stuck on, the homework is due in a few hours and its my last problem. (any help would be appreciated!!)(adsbygoogle = window.adsbygoogle || []).push({});

______________________________________

A charge of 3.93 μC is held fixed at the origin. A second charge of 3.93 μC is released from rest at the position (1.15 m, 0.550 m).

Enter scientific notation as 1.23E4.

(a)

If the mass of the second charge is 3.33 g, what is its speed when it moves infinitely far from the origin?

----i found this number to be 8.10 m/s which is correct

(b) (so this is the part i need help with.....)

At what distance from the origin does the 3.93-μC charge attain half the speed it will have at infinity?

im probably just having a brain fart but i can't seem to put it together....:surprised
