- The cheetah is considered the fastest running animal in the world. Cheetahs can accelerate to a speed of 21.8 m/s in 2.50 s and can continue to accelerate to reach a top speed of 28.8 m/s. Assume the acceleration is constant until the top speed is reached and is zero thereafter. 1) Express the cheetah's top speed in mi/h. (Express your answer to three significant figures.) answer: 64.2 2) Starting from a crouched position, how long does it take a cheetah to reach its top speed? (Express your answer to three significant figures.) answer: 3.31 3) How far does it travel in that time? (Express your answer to three significant figures.) answer: 47.5 4) If a cheetah sees a rabbit 120 m away, how long will it take to reach the rabbit, assuming the rabbit does not move? (Express your answer to three significant figures.) answer: ? tried 5.25 and 5.26 but does not workA car is traveling east at 17.5 m/s when it turns due north and accelerates to 32.5 m/s, all during a time of 5.00 s.
