Representation: 0 1 A helicopter is flying due south with speed vi = 27 m/s. 2 Physics Concept(s): 1 2 Then it begins accelerating in a direction 0 = 10 north of 0 0.5 1 east with magnitude a. After t seconds have passed, the Initial Equation(s): helicopter's velocity vector now points due east. What is Symbolic Answer: 0 the helicopter's speed vf at this moment? As part of your Units Check: 0 0.5 1 representation, draw a tip-to-tail vector addition diagram Neatness: -2 -1 0 that relates together vi, Uf, and Av. Total: Correct Answer: Y N Representation Physics Concept(s) (Refer to the list of concepts on Carmen under modules/course documents.) (1)Initial Equation(s) Algebra 1Work (Symbols only.
