Homework Help: Physics (Checking answe)

Posted by Edwin on Sunday, October 24, 2010 at 3:52pm.

Sorry for re-posting but I need to know if I did it right, please help, I worked out the problem I just want to know if I did it right.

A shopper in a supermarket pushes a cart with a force of 35 N directed at an angle of 52(angle sign here) downward from the horizontal. Find the work done by the shopper on the cart as the shopper moves along a 50.0 m length of aisle.

Someone tell me if this is right:

W= (35.0N) (50.0m)(cos25.0)

W= 1586 J

If not please show me how to do it.
