To move a large crate across a rough floor, you push on it with a force F at an angle of 210 below the horizontal, as shown in the figure. Find the force necessary to start the crate moving, in newtons, given that the mass of the crate is 35.0 kg and the coefficient of static friction between the crate and the floor is 0.569. Decompose the force F into the horizontal and vertical components. Calculate the normal force using Newton's Second Law: what pulls up equals what pulls down. Calculate the maximum force of static friction using Eq. 6 3
