The block in the figure below has a mass 5.6 kg and it rests on an incline of angle 8. You then push on the block with a force of F = 37 N, directed up the slope as shown. Assume the incline is smooth and determine the angle of the incline if the block moves with constant speed. 38.62 x Did you draw a free body diagram and identify the forces acting on the block? Take the x direction to be parallel to the incline and the y direction to be perpendicular to the incline.º Submit Answer F OC

When traveling on an airplane you get meals on a serving tray that has large coefficients of static and kinetic friction between the tray and dishes on it. Assume the airplane is moving from left to right. Assume also that the tray is parallel to the velocity of the airplane. d. Draw a force diagram for a cup on a serving tray as seen by a stationary observer on Earth if the airplane is on a runway and speeding up; the cup is at rest on the tray.

Block 1 (10 kg) is located on the surface of a table. A rope pulls on block 1 with a horizontal tension of 58 N to the right and a vertical tension of 60N upward. The coefficient of kinetic friction between the block and the surface equals 0.2. On a sheet of paper, draw the free body diagram for block 1 using the two- subscript notation from class. After completing the free body diagram, enter below each force and its x & y-components. Remember that the x-component is the "i" component and the y-component is the "j" component.
