Homework Statement
A 2 kg block is at rest on a horizontal surface with which its coefficient of static friction is 0.3. Determine the minimum force F that must be applied to the block at an angle of 53 degrees below horizontal in order to move the block (see Figure 2).

The Attempt at a Solution
I was unable to take good notes this past lecture because I was not at a decent seat, and based on what I do have, this is what I had come up with:
##(0.3)(2)(9.8)cos53^o##
##= (5.88)(0.60)##
##= 3.5 N##
I know this cannot be right.
Could someone please explain to me how we could find the minimum force (while pointing towards a specific formula I should look into)?
