Is this right? If F=ukN with F being the reading on the spring scale when the box is being pulled at constant speed F=usN with F being the reading on the spring scale when the box starts to move.

[b]1. If a wooden box was pulled up the inclined plane at a constant speed using a spring scale. How would an equation be derived for uk, us, Ff, and N. Homework Equations So to get N. The equation would be N=mg-F (sin (theta)). with F being the reading on the spring scale. Ff would be...

Ive been trying to get this problem. I already have the answers but I want to know how to solve it. An airplane with a speed of 77.5 m/s is climbing upward at an angle of 34.1 ° with respect to the horizontal. When the plane's altitude is 585 m, the pilot releases a package. (a) Calculate...
