Answer 2

Answer:

v = 57 m/ s

a = 24 m/ s²

Step-by-step explanation:

s(t) = 12t²- 15t + 30

v = ds/ dt

= 2. 12t - 15

= 24t - 15 m/ s

a = dv/ dt

= 24 m/ s²

at t = 3 seconds

v = 24 × 3 - 15

= 72 - 15

= 57 m/ s

a is independent of variable t as it's value is always 24 m/ s²

derivatives used :-

• d/ dx ( a^ n ) = n a ^ (n - 1)

• d/ dx ( bx) = b

• d/ dx (constant) = 0
