Physics Homework Help.

I have two questions from a worksheet that i am having problems over. It is over Newton's laws. They are:

A late traveler rushes to catach a plane, pulling a suitcase with a force directed 30.0 degress above the horizontal. If the horizontal component of the force on the suitcase is 60.6 N, what is the force exerted on the handle. I believe the answer is 70.0 N, but don't know how to get the answer.

Next,

A book with a mass of 2.0 kg is held in equilibrium on a board with a slope of 60.0 degress by a horizontal force. What is the normal force exerted by the book? Don't know what the answer is.

If anyone can I would like a explotation how to get the answers and how to figure them out. Private msg. me if they get legthy by any means. Thanks.

1.) 60.6N/cos(30) = 70N

for the second one I don't remember how to for sure, so I don't want to give you a false answer.

well these are multiple choice so what do get and I can see if one of them is correct. But if it was right I would like to know how you got it and what you had to do.
