Hello,
Yes, this is for a class - but it is simply a high school homework assignment.
I am solving for v. (This is only part of the homework problem, BTW).

My question is particularly concerned with the last two lines. On the final line, is the $$-64/5$$ necessary?

Thanks,
Mitchell

of course. you can verify that otherwise, the original differential equation is not satisfied.

Thanks man. I guess I just wasn't thinking.

BTW, I am very impressed by these forums. It is a great resource and there are many interesting things to read.

Thanks,
Mitchell

It's great. There are so many knowledgable people around. I sometimes feel like I'm learning more here than I do at school for 3000\$ a year. :grumpy:
