Question

If a man has a velocity varying with time given as v = 3t2 , then :Find out his acceleration after 3 seconds​

Answer 1

Explanation:

there is velocity differentiate to acceleration

v=3t²

=d/dt(3t²)

=6t

a=6t(where t=3s)

a=18m/s²

Answer 2

Answer:

v=3t^2

acceleration =dv/dt

d(3t^2) /dt acc to differentiation rule

3×2t you should learn the rules

6t

time 3 second

6×3 =18
