In the figure below, a force F1 of magnitude 6.70 units acts on a crate at the origin in a direction θ = 25.0° above the positive x-axis. A second force F2 of magnitude 5.00 units acts on the crate in the direction of the positive y-axis. Find graphically the magnitude and direction (in degrees counterclockwise from the +x-axis) of the resultant force F1 + F2. Two forces act on a crate. Force vector F1 acts up and to the right on the right side of the crate at an acute angle θ above the horizontal. Force vector F2 acts vertically upwards on the top side of the crate.

Suppose that F = 880 lb . (Figure 1) Part A Determine the magnitude of the resultant force. Express your answer to three significant figures and include the appropriate units. FR = 1150 lb Part B Determine its direction, measured counterclockwise from the positive x axis. Express your answer using three significant figures.

The 50-kg crate is pulled by the constant force P. The crate starts from rest and achieves speed of 10 m/s in 5 s. The coefficient of kinetic friction between the crate and the ground 0.2. Part A Determine the magnitude of P. Express your answer to three significant figures and include the appropriate units
