Posted by Chelsea on Wednesday, October 31, 2012 at 6:58pm.

An object with a mass of 12 kg slides 9 meters across a horizontal surface with a coefficient of kinetic friction of 0.22. For the duration of the slide an external force, F1, with a magnitude of 43 Newtons acts on the mass in the positive y direction while another force, F2, is angled at 33 degrees above the x axis. The net work done over the distance of 9 meters, 414 Joules. What is the magnitude of F2 in Newtons?
