Transcribed Image Text:An object of mass 9 kg is released at point A, slides to the bottom of the 30° incline, then collides
with a horizontal massless spring, compressing it a maximum distance of 0.75 m. The spring
constant is 400 N/m, the height of the incline is 2.0 m, and the horizontal surface is frictionless
(there is friction on the incline surface).
