$\huge\mathtt \red{A} \blue{n} \pink{s} \purple{w} \blue{e} \orange{r}$

Given:-

☆Displacement = x = 3 - 5t + 2t × 2.

To Prove:-

☆Velocity and Acceleration

Solution:-

☆Using Formula,

${ \boxed{ \boxed{ \boxed{ \bold{ \orange{v = \frac{d \times x}{d \times t} }}}}}} </p><p>v= d×td×x$

》0 - 5 + 22 × t

》4t - 5

☆Now, velocity at 2 seconds :

》4 × 2 - 5

》8 - 5

》3 m/s

☆Hence, Instantaneous velocity at time of 2 seconds = 3 m/s.

☆Now, Instantaneous acceleration : 4 - 0 = 4 m/s².
