The crate shown is held against wedge B by a spring. The spring is 96.0% of its original uncompressed length l= 3.00 m, and the spring constant is given as k = 1750 N/m. The coefficient of static friction at all contacting surfaces is ls = 0.150. The mass of the crate is m = 23.0 kg. The angle is 0 = 13.0°. Neglect the mass of the wedge. Assume the crate only moves in the y direction and that wedge A cannot move.

The crate shown is held against wedge B by a spring. The
spring is 96.0% of its original uncompressed length
l= 3.00 m, and the spring constant is given as
k = 1750 N/m. The coefficient of static friction at all
contacting surfaces is ls = 0.150. The mass of the crate is
m = 23.0 kg . The angle is 0 = 13.0°. Neglect the mass of
the wedge. Assume the crate only moves in the y direction
and that wedge A cannot move.
