This is a problem from my Physics 101 class that I'm having trouble solving. I'm not sure what equations I'm supposed to use. 1. The problem statement, all variables and given/known data To move a large crate across a rough floor, you push on it with a force F at an angle of 21° below the horizontal. Find the force necessary to start the crate moving, given that the mass of the crate is m = 34 kg and the coefficient of static friction between the crate and the floor is 0.48. 2. Relevant equations N= mgcosѲ = 311.386N W= mgsinѲ = 119.53N fs,max = mews*N = 149.465N ΣF = N + fs + W 3. The attempt at a solution Eek I don't know! That's why I'm posting!
