An object weighing 500kg is to be pulled by a man by exerting a force P. Force P is inclined at an angle of 25 deg. measured from the positive axis. The object and the floor has a coefficient of friction: static = 0.35 and dynamic = 0.15. %3D 1. What is the minimum magnitude of P needed to start the object to displace horizontally?
