Question: You are designing a delivery ramp for crates containing exercise equipment The l470-N crates will move at 1.8 m/s at the top of a ramp

You are designing a delivery ramp for crates containing exercise equipment The l470-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 550-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 8.0 m along the ramp. Once stopped, a crate must not rebound back up the ramp. Calculate the force constant of the spring that will be needed in order to meet the design criteria.
