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, as shown in the figure. Find the force necessary to start the crate moving, given that the mass of the crate is m = 29 kg and the coefficient of static friction between the crate and the floor is 0.64.

help me solve this. thanks
