Learning Goal: To use the equations of equilibrium to analyze a system containing a wedge and to determine the necessary applied force to introduce motion into the system. The crate shown is held against wedge B by a spring. The spring is 94.5% of its original uncompressed length 12.50 m, and the spring constant is given as k=1450 N/m. The coefficient of static friction at all contacting surfaces is μ, = 0.120. The mass of the crate is m 28.0 kg. The angle is 0=10.0°. Neglect the mass of the wedge. Assume the crate only moves in the y direction and that wedge A cannot move.( Figure 1) Part A - Determining the normal force exerted by the crate on the wedge Determine the normal force No that the crate exerts on the wedge when the system is at rest. Express your answer to three significant figures and include the appropriate units. ▸ View Available Hint(s) ? Nc = Value Units Submit Part B - Finding the smallest horizontal force P to move the crate upward Determine the magnitude of the smallest horizontal force P that is necessary to begin moving the crate upward.
