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
