me with this force problem, Thank you

[Leocardinal]

Homework Statement

A 70 kg crate is pushed at constant speed up the frictionless 23°

What horizontal force F is required? ( x Component Force)?

What force is exerted by the ramp on the crate?

Homework Equations

I used wsin(23) then i did (wsin(23))cos(23) which i found 246.73 N

and I used Wcos(23)= 631 N

I know that Fnet= 0 since the Velocity is constant acceleration is zero

I did a freebody Diagram

The Attempt at a Solution

I got 246.7 N for force in the Horizontal direction

and I got 631 N for what the second question is asking for.

I did that by calculating the Normal force.

Please Help

It's a bit hard to tell what you did. Start by identifying all the forces acting on the crate. Then write two equations: One for force components parallel to the incline; the other for components perpendicular.
