Sorry if this is in the wrong section, I wasn't sure where to post it.(adsbygoogle = window.adsbygoogle || []).push({});

Can anyone help me - I need to solve the following differential equation and find the values of c and B.

> k is given as -98.3146.

> v = 55 when t = 9

> v = 50 when t = 10

k(v^2) + B = m.(dv/dt)

Am I right in thinking that by separation of variables and integration I get

arctan(v/sqrt(B/k))=kt/m + c

??

But then if so, how do I find the values of c and B?

Thanks for any help,

Simon.
