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.
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.
N= mgcosѲ = 311.386N
W= mgsinѲ = 119.53N
fs,max = mews*N = 149.465N
ΣF = N + fs + W
Eek I don't know! That's why I'm posting!
