1. The problem statement, all variables and given/known data A mover's dolly is used to deliver a refrigerator up a ramp into a house. The refrigerator has a mass of 110 kg. The ramp is 2.1 m long and rises 0.42 m. THe mover pulls the dolly with constant velocity and with a steady force of 445 N up the ramp. The dolly and ramp constitute a machine. g=9.81/s^2 What work does the mover do? The attempt at a solution well i thought that this was a simple question. I used W=F*x using 445 N as F and 2.14 M as x which i got from using the pythagorean theorem. My final answer was 953.007 J but it was incorrect. Can someone help me understand what I'm doing wrong?
