Problem Set A

 

Problem 5:

Anna Litical is doing the It's All Uphill Lab. She applies a 17.9-Newton force parallel to the inclined plane in order to pull a cart up a hill inclined at an angle of 53 degrees. If she drags the cart a distance of 1.39 meters, then how much work (in Joules) does she do upon the cart?
