1. The problem statement, all variables and given/known data I have been trying this question for close to two hours now and have gotten it incorrect three time. I would appreciate any help! The spring has a constant of 30 N/m and the frictional surface is .3 m long with a coefficient of friction μ = 1.02. The 4 kg block depresses the spring by 17 cm, then is released. The first drop is 1.4 m, then it is on the .3 m lonf frictional surface, and the second drop is 1 m. How far from the bottom of the cliff does it land? Answer in units of m. I posted the same question on cramster so I could draw you a picture. http://answerboard.cramster.com/physics-topic-5-151971-0.aspx 2. Relevant equations 3. The attempt at a solution I tried to find the energy stored in when it is compressed at distance 1 by doing w = Fd w = (30)(.17) After that, I tried to find the time it took to fall at both place, but I fell short of information. And then I tried to use the formula Wf = cf*M*g*d2, but I wasn't sure what went where. Now I am at a dead end and am extremely confused. Will someone please help?!?!!?
