The velocity v of a particle moving in the xy plane is given by v (5.9t – 4.6t2 )i + 8.3j, with v in meters per second and t (> 0) in seconds. At t = 2.7 s and in unit-vector notation, what are (a) the x component and (b) the y component of the acceleration? (c) When (if ever) is the acceleration zero? (d) At what positive time does the speed equal 10 m/s?
