Question

a cheetah can run from 0 to 70 mph in 2.2 seconds.
what is the cheetah's top speed in m/s?

Answer 1

Its top speed is 72 mph.

Note  1 mile = 1852 meters.
          1 hour = 3600 seconds

Therefore  72 mph =  72 miles / 1 hour
                               =    (72*1852 meters) / (1 *3600 seconds)
                               =  133344/3600   meters/seconds
                               =  37.04  m/s

Answer 2

The top speed of cheetah in m/s is 31.29 m/s.

Given data:

The initial speed of Cheetah is, u = 0 mph.

The final speed of Cheetah is, v = 70 mph.

The time interval is, t = 2.2 seconds.

We are already given with top speed of Cheetah, and its non other than the final sped itself. Now we need to convert the mph value of top speed into m/s value.

We know that,

1 mph = 0.44704 m/s

So, value of 70 mph in m/s is,

$=70 \;\rm mph \times \dfrac{0.44704 \;\rm m/s}{1 \;\rm mph}\\\\=31.29 \;\rm m/s$

Thus, we can conclude that the top speed of cheetah in m/s is 31.29 m/s.
