Answer 2

$\sf \color{blue}{\bigstar}$ ANSWER :

$\frac{ds}{dt}$ = v = 4b³ - 30t² + 48t + 36

$\frac{dv}{dt}$ = (2t² - 60t + 48) = 0

→ l² - 5t + 4 = 0

Minima and Maxima,

l = 4 and t

$\frac{dw}{dt^{2}}$ = 2t - 5

→ t = 1 (–)

→ t = 4 (+)

t = 4, taken Minima !

✓ Hence, Option D) 4s is the correct answer...!!
