two problems in particular, one i got in calc, the other in physics(adsbygoogle = window.adsbygoogle || []).push({});

one asks if [tex] a = -v [/tex]

and [tex]v = 1[/tex] when [tex] t = 0 [/tex]

what is a possible position function for this equation

the other one is

given [tex] a = 3x [/tex]

and starting at rest from [tex]x = 0[/tex]

find the velocity at 5 seconds

i cant seem to get the concept behind these, because the times we do them are so far and few between
