1. The problem statement, all variables and given/known data The block of ice weighs 500N. It is being pushed up an inclined plane with a height of 3m and a hypotenuse of 6m. 1a. How much force is need to push it to the top? 1b. How much work is required to push it to the top? 2. Relevant equations W=Fd=deltaKE=deltaGPE 3. The attempt at a solution I have no idea for 1b. because W=Fd, the force is 500N, and d would have to equal 3m to get the 1,500J needed. However, if this is true, and the force is parallel to the motion, why wouldn't you use the hypotenuse instead of the height for the distance? 1b. GPE at the top = (500N)(3m) = 1,500J Thus, W = Fd 1,500 J = F(6m) = 250N Is this correct? Thanks!
