you are designing a delivery ramp for crates containing exercise equipment. the 1470-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 crates 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 create 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
