Question

Just wanted to make sure I answered this correctly,its been a while... a) What is the mass of a book that weighs 3.2N at a pointwhere g=9.8m/s2? b) At the same location, what is the weight of a dog whosemass is 14kg? For a) I got .33kg For b) I got 137.2N I solved a) like this: F = ma where a = g, F = 3.2N and solve for m 3.2N = m(9.8m/s2) m = (3.2N)/(9.8m/s2) m = .33 Answer will be in kg units I solved b) like this: F = ma where a = g, m = 14kg and solve for F F = (14kg)(9.8m/s2) F = 137.2 Answer will be in N units Let me know if I did this right or not. If not let meknow where I screwed up. Question is from University Physics11th edition by Young and Freedman, page 149. Number 4.18 Thanks!
