a. They were able to observe their tracks in cloud chambers. b. Scientists were confident in the law of Conservation of energy. c. They were able to calculate exactly how much mass...
I think a) is (b-y)^2 + x^2 = L^2; the second derivative of this can be taken to get the actual accelerations. I can't get b) though. Have been stuck on this for a while! Thank you!...
