11. (10 points) A sled and a member of the OSU Dinos ultimate "frisbee" team are on top of a 15 -meter-high hill. Together the sled and Dino total 25 kg. They compress a spring of spring con- stant k = 20,000 N/m by 30 cm from equilibrium. The sled is then released and slides down the frictionless ice-covered hill, across a 10-meter-long patch of rough snow with p = 0.20, s = 0.56. Twenty meters after the rough patch is an ice wall at point P. Attached to the ice wall is a spring of spring con- stant k = 10,000 N/m. How many times will the sled and Dino pass across the rough patch of snow before coming permanently to rest? d2 = 20 m d = 10 m k2 book P 21000 h = 15 m SISTEM: M, & Ed S, & SURMACE y= 51 + U U ? + + Th i + = 4Eth : # OF TIMES SLED PASSES OVER Rough PATCH Mgy + x = = - Ffm Narcosop NAR Mx FN Ndi Love poe Efy-myy /// Mgh + k, X, ? = Nx mg di N 9.34 times (9.337) F~= mg - why they use Eth E Th Rubric 1 pt - Identif 4 pts - Appli 1 pts - Reali 2 pts - Work 1.5 pt - N*v 0.5 pts - An 0 a Are all The internal Fores here?
