Review 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 Bby a spring. The spring is 93.0% of its original uncompressed length 1 = 2.50 m, and the spring constant is given as k = 1650 N/m . The coefficient of static friction at all contacting surfaces is My 0.120. The mass of the crate is m = 30.0 kg . The angle is 6 = 15.0° Neglect the mass of the wedge. Assume the crate only moves in the y direction and that wedge A cannot move. (Figure 1) Determine the normal force Nc 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) ol i uA ?
