Homework Statement
In the figure, a crate of mass m = 111 kg is pushed at a constant speed up a frictionless ramp (θ = 30°) by a horizontal force F . The positive direction of an x-axis is up the ramp, and the positive direction of a y-axis is perpendicular to the ramp. (a) What is the magnitude of F ? (b) What is the magnitude of the normal force on the crate?
Homework Equations
The Attempt at a Solution
For part A, I got 628.67 N which is correct.
I do not have part B, but I do have some other information that I found, which is correct.
Gravitational Force along x-axis is -544.455 N
Fx component of the applied force is 544.45 N
Fy component of the applied force is -314.341 N
Y component of the gravitational force is -943.023 N
Acceleration components are zero.
And the normal force of the crate is in the positive direction of the y-axis.
Anybody know how to get part B?
