Harry and Ashley were pulling a sled. Harry pulled at 15 degrees West of South at 400N and Ashley pulled at 50 degrees North of West at 375N. They encountered friction to the east at 150N. Calculate the overall force (Fnet) on the sled, using a scaled vector drawing. Use a scale of 50N to 1 cm.
I have the drawing finished, but I don't know how to figure out Fnet? I am really confused...
A rightward force is applied to a 10-kg object to move it across a rough surface at constant velocity. The coefficient of friction, µ, between the object and the surface is 0.2. Draw a free body diagram to determine the graviational force, normal force, applied force, frictional force, and net force. Neglect air resistance.
For this one, I have the diagram, basically a square with an arrow from each Side
Upwards is Fnorm, Right is Fapp, Downwards is Fgrav, and Left is Ffric.
I have no idea how to do this one either. I'd appreciate some help, thanks.
