1. A particle moves in the ac y plane With a time-dependent position vector given by: m) = (At):& + (Bi 09);"; where A = 10 m/s: B = 20 m/s, and C = 5 m/sz. (a) Calculate 17(35) and (1'05). (b) Does this particle have constant acceleration? (0) Does this particle's motion have a turning point in the 9: and/or y dimensions? If so, at what time(s) do these turning points occur
