Question

The acceleration of particle varies with time
as: a(t)= 3t? +4. If the initial velocity of
particle is 2 m/s, find the velocity of particle
att = 3 sec
(A) 41 m/s
(B) 4 m/s
(C) 39 m/s (D) 27 m/s​

Answer 1

Answer:

answer is 41 m/a

plzzz mark as brainlist and follow me

Answer 2

Answer:

Given= 3t³+4

T = 3 sec

Then

V-2= 3t³+4t

v-2= 3×3²+4×3

V-2=27+12

V-2=39

V =41

Therefore correct Answer is Option A
