You proved for #3 that the maximum is 1.1 and from = 1.05 K K = ½Mv2, vmax J m/s. Around 5.65 I had to read the graph and find the other place where was -16.67 U m. J, because the is -16.67 The situation where equals is the situation of rest, ME U ME J. because and = 0 is a distinctive condition. At rest are the two points U = ME K, K – where the mass turns around. These two points are 5.65 and _____ m m. Same answer as #2, silly. Do you not know the definition of equilibrium? #6 is a new situation. The old situation had an ME of -16.67 J. the ME of this new What’s situation: ____ J. the key to solving this. That’s Answer: The other place where equals about -17.2 You prove that answer. For every single U J. thing spelled out for the reader, read the next page, but please only as a last resort. Every Single Thing Spelled Out for the REader: The blank to fill in on the #4 discussion above was 8 m. The proven solution to #6 is: Ui + Ki = Uf + Kf The new is -17.2 because = -17.2 (from graph) and = 0. ME Ui Ki J, J -17.2 + 0 = Uf + Kf gets me what solving for, and there = _____ (hidden Uf Kf I’m J given.) It was zero for The thing stops and changes direction. So this happens where = -17.2 Kf. Uf J, because is always -17.2 and is 0, and The location where = -17.2 is at ME Kf U = ME – K. Uf J J just over 7.8 the answer to #6. That’s m.
You proved for #3 that the maximum K is 1.1 J and from K = ½Mv2, vmax = 1.05 m/s. Around 5.65 m. I had to read the graph and find the other place where U was -16.67 J, because the ME is -16.67 J. The situation where U equals ME is the situation of rest, because U = ME – K, and K = 0 is a distinctive condition. At rest are the two points where the mass turns around. These two points are 5.65 m and _____ m. Same answer as #2, silly. Do you not know the definition of equilibrium? #6 is a new situation. The old situation had an ME of -16.67 J. What’s the ME of this new situation: ____ J. That’s the key to solving this. Answer: The other place where U equals about -17.2 J. You prove that answer. For every single thing spelled out for the reader, read the next page, but please only as a last resort. Every Single Thing Spelled Out for the REader: The blank to fill in on the #4 discussion above was 8 m. The proven solution to #6 is: Ui + Ki = Uf + Kf The new ME is -17.2 J, because Ui = -17.2 J (from graph) and Ki = 0. -17.2 J + 0 = Uf + Kf Uf gets me what I’m solving for, and there Kf = _____ (hidden given.) It was zero for Kf. The thing stops and changes direction. So this happens where Uf = -17.2 J, because ME is always -17.2 J and Kf is 0, and U = ME – K. The location where Uf = -17.2 J is at just over 7.8 m. That’s the answer to #6.
