Answer :
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,
[tex] \frac{ {v}^{2} - {u}^{2} }{2as} [/tex]
So, in order to get the value of a, let's do:
[tex]a = \frac{ {v}^{2} - {u}^{2} }{2s} [/tex]
Now substitute all the given values. So,
[tex]a = \frac{ {5}^{2} - {3}^{2} }{2 \ \times 2} [/tex]
[tex]a = \frac{25 - 9}{4} [/tex]
[tex]a = \frac{16}{4} [/tex]
[tex]a = 4 \: m / {s}^{2} [/tex]
Note:- You can also write the answer as:
[tex]4 \: m. {s}^{ - 2} [/tex]
Therefore, the answer is 4 m/s² or 4 m.s^-2
