i know and think that the when the mass inreases, the speed of the coaster does not change... this is according to researching on some sites simulators... it hinkt thats right...(adsbygoogle = window.adsbygoogle || []).push({});

and because the speed esont change, the time doesnt change?

but when i think about it more, im nto sure because i cannot prove it with the conservation of energy equation... or at least i dont think im right, cuz if the i put it into the equation where you have the Ek=1/2mv^2, then when mass gets larger, then the energy will get larger...

i dont know what im talking about, im very confused.
