You are designing a delivery ramp for crates containing exercise equipment. The 1330 N crates will move at 1.8 m/s at the top of a ramp that slopes downward at 22.0. The ramp exerts a 515 N kinetic friction force on each crate, and the maximum static friction force also has this value. Each crate will compress a spring at the bottom of the ramp and will come to rest after traveling a total distance of 5.0 m along the ramp. Once stopped, a crate must not rebound back up the ramp.

Calculate the largest force constant of the spring that will be needed to meet the design criteria.
