Question

Velocity of a particle varies with time as v= (3t^2 +2t)i cap m/s.Initially the particle is ar x=2m .At t=2 second ,particle will be at x =​

Answer 1

Answer:

Correct option is

correct answer is B.

a = 3t² + 2t + 2

dv = adt

B 18 m/s

Ya 46

Open in answrapp

V= 3t³ + 2t² 3 2 +2t

v = t³ + t² + 2t

att = 0, u = 2

att 2

v = t³ + t² + 2t + 2

= 8 +4+2 X 2+2

=8+4+4+2

= 18m/s
