The world's fastest land animal, the cheetah, can accelerate at 8.15 m/s² to a top speed of v_cmax = 33 m/s. A cheetah observes a passing gazelle traveling at v_g = 18.4 m/s and begins to chase it. How long, in seconds, does it take the cheetah to reach its maximum velocity, v_cmax, assuming its acceleration is constant?
