Question

I need help with the second part of this question. Please show work so I can see. Thanks.

I. The fastest land mammal, the cheetah, can accelerate from 0 mi/hr to 70.0 mi/hr in 3.0 seconds. What is the acceleration of the cheetah? Give your answer in units of mph/sec. I got 23.3 for my answer.

The Lamborghini Diablo sports car accelerates from 0.0 km/hr to 99.2 km/hr in 4.0 seconds. What is the acceleration of this car? Give your answer in units of kilometers per hour/sec. 7.
I got 24.8 kph/s as the answer for the above.

II. Which has a greater acceleration, the cheetah or the Lamborghini Diablo? (To figure this out, you must remember that there are 1.6 km in one mile) Be sure to show your calculations

Answer 1

SInce 1 mi = 1,6 km,
1 mi/hr/s = 1.61km/hr/s
So,

23.3 mi/hr/s = 37.5 km/hr/s

So, now you can compare them.

Answer 2

How did you do the work? I don't see it, not getting it.
