Homework Statement
To move a large crate across a rough floor, you push on it with a force F at an angle of theta=21.0 degrees below the horizontal. Find the force necessary to start the crate moving, given that the mass of the crate is 32.0 kg and the coefficient of static friction between the crate and the floor is 0.600.
Homework Equations
Fcos(theta)=Coefficient of static friction*mg
The Attempt at a Solution
F= [(0.600)(32)(9.81)] / cos(21)
F= 202N
I entered this answer, but the system says that it is wrong and it told me that "the normal force is not equal to the weight here." So I am not sure what I'm doing wrong, but I'm close to the right answer?
Thank you very much.
