Answer:

24.2 s

29.2 m

Explanation:

First, convert each speed from km/h to m/s.

91.5 km/h = 25.42 m/s

77.5 km/h = 21.53 m/s

The speed of the cheetah relative to the gazelle is:

v = 25.42 m/s − 21.53 m/s

v = 3.89 m/s

So the time it takes for the cheetah to catch the gazelle is:

x = v t

94.2 m = (3.89 m/s) t

t = 24.2 s

If instead we want to find x so that t = 7.5 s, then:

x = v t

x = (3.89 m/s) (7.5 s)

x = 29.2 m

An object with an initial velocity of 27 m/s has a final velocity of 39 m/s after 13 seconds.
grigory [225]

Answer:

<h3>The answer is 0.92 m/s²</h3>

Explanation:

To find the acceleration of an object given it's initial and final velocity and time taken we use the formula

a =  \frac{v - u}{t}  \\

where

v is the final velocity

u is the initial velocity

t is the time taken

a is the acceleration

From the question

v = 39 m/s

u = 27 m/s

t = 13 s

We have

a =  \frac{39 - 27}{13}  =  \frac{12}{13}  \\  = 0.923076... \:  \:  \:

We have the final answer as

<h3>0.92 m/s²</h3>

Hope this helps you
