Question

hello...
can you help me,to answer from the quetion below..and can you explains the basic theory....

question :
A marble dropped ,which initially at rest,dropped on the oil box.This marble accelerated as function of velocity :A-Bv,with A and B are constant.find is velocity as time function....

thank's...

Answer 1

thank's so much...

Answer 2

\[a=A-Bv\]
\[\int\limits_{0}^{v}dv/(A-Bv)=\int\limits_{0}^{t}dt\]

Evaluating this gives the velocity as a function of time!! Easy!!
