Answer 1

$\huge\underline\mathfrak{Answer}$


Displacement of particle at time (t). = 200 m



$\huge\underline\mathfrak{Solution}$


$\textbf{Step-by-step-Solutions}$


$\textbf{Given}$

magnitude of velocity (speed)=10m${s}^{-1}$

Acceleration=2m ${s}^{-2}$

Time=10s



$\textbf{Formula used}$

Equation of motion


$s = ut + \frac{1}{2} a {t}^{2}$

put the given value in eq ,we get


$s = \: (10 \times 10) + \frac{1}{2} \times 2 \times 100$

$s = 100 + 100$

$s = 200m$



$\huge\underline\mathfrak{Hence}$

So, Displacement of particle is = 200m



$\textbf{Note}$

According , to me I think you are puzzle in velocity and speed you thought that there is speed given and how we put it into motion eq

so let us discuss on one think that what is velocity and speed their magnitude is samebut not direction and here we can use magnitude .so we can consider here speed as velocity because here direction is not given but ans is depend on magnitude only .
