Homework Help: Physics

Posted by Fatima on Wednesday, December 22, 2010 at 5:06pm.

The problem goes like this...
You are pushing a shopping cart at a constant speed. The handle makes an angle of 30.0 degrees with the horizontal and the friction in the cart has a coefficient of 0.400 to account for all the axles, etc. The mass of the cart is 45.0-kg and we are pushing it a distance of 35.0 meters along a level floor. Find the "normal" force and the work due to that force.

I know that the answers are 573 N and 0 J respectively but I don't know how to get these answers. Please help!
