Don't be retarded, draw a picture, resolve forces and remember Newton's first law.

>constant speed
Acceleration is zero. That means the net force is zero. The three forces are gravity, F, and the normal force. Think of what the box would do if F wasn't there, and use that to find the normal force.

there is no mention of gravity so he should ignore it

Generally it's assumed, as the two problems make more sense with gravity assumed.

You just plug and chug with some trig
