Could I get the solutions to number 6 parts c and d. I have gotten a and b with no problem but I am stuck on how to approach c and d.

Thanks!

I am also struggling with your answer to 6c.  Maybe there is something that I am misunderstanding about the question.  I have used conservation of energy to solve it and I end of with a quadratic equation.  But I am getting 1.5 m instead of 2.5.

Kim, I apologize for the late response. I'm emailing you my solutions for #6 and #10 - #6 didn't have a numerical solution, but #10 did, so I'm guessing that's the problem where you got 1.5 m instead of 2.5 m.  John

Kim, my email to you with the problems bounced back - do you have another email I can send it to?  John

Hi John, could I also have the solution for 6c please? Thank you

Caroline, I'll email the whole solution to you.  John
