Okay we've got a calc quiz on related rates tomorrow and I'm so completely lost I thought I'd ask and see if anyone can tell me how to this problem, if I can learn from that its at least a start hehe.
A man 6 feet fall walks at a rate of five feet per second away from a light that is 15 feet above the ground. When he is 10 feet away from the base of the light,
a.)at what rate is the tip of his shadow moving?
b.)at what rate is the length of his shadow changing?
If you have any insight as to the steps I should take to solve these I would be most appreciative. As a reminder this isn't homework but me studying so I hopefully don't flunk a quiz so don't feel like telling me how is wrong hehe.
Thanks!
