To analyze the behavior of black bears during the night. To describe how black bears adapt to life near human. To evaluate the decline in the number of black bear.

Answer 2

Acceleration = 4 m/s²

Step-by-step explanation:-

Let's solve this question easily...

Given,

Initial velocity (u) = 3 m/s

Final velocity (v) = 5 m/s

Displacement (s) = 2m

Using the formula,

$\frac{ {v}^{2} - {u}^{2} }{2as}$

So, in order to get the value of a, let's do:

$a = \frac{ {v}^{2} - {u}^{2} }{2s}$

Now substitute all the given values. So,

$a = \frac{ {5}^{2} - {3}^{2} }{2 \ \times 2}$

$a = \frac{25 - 9}{4}$

$a = \frac{16}{4}$

$a = 4 \: m / {s}^{2}$

Note:- You can also write the answer as:

$4 \: m. {s}^{ - 2}$

Therefore, the answer is 4 m/s² or 4 m.s^-2
