The velocity v→ of a particle moving in the xy plane is given by , with v→ in meters per second and t (> 0) in seconds. at t = 1.6 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?
