Help Me Please!! You don't have to actually do this, but does anyone know how to so I can solve it myself? :uhh: 1) A 50 Newton horizontal force is needed to keep an object weighing 500 Newtons moving at a constant velocity of 2.0 m/s across a horizontal surface. What is the magnitude of the frictional force acting on the object? 2) A 40 kg mass is moving across a horizontal surface at 5 m/s. What is the magnitude of the net force required to bring the mass to a stop in 8 seconds? PLEASE HELP!!! Thanks!
