ok, thank you very much. I'll try it out.

oh ok. thank you. it's a multiple choice question and most formulas I found already had an initial speed given so I tried substitution. I tried to calculate the speed in m/s if both masses travel 8cm. then i multiplied the masses w/ the velocity. 0.01 X velocity = 2.0 X velocity =...
