The spring has a constant of 12 N/m and the frictional surface is 0.2 m long with a coefficient of friction µ = 1.78 . The 5 kg block depresses the spring by 15 cm, then is released. The first drop is 2.8 m and the second is 2 m. The acceleration of gravity is 9.8 m/s 2 . µ h L h m k x 1 2 s How far from the bottom of the cliff does it land? Answer in units of m.
