Question

A particle with an initial velocity of 12 m/s has its acceleration modeled by the equation a(t) = t 2 + 3. Find the particle’s velocity at t = 2

Answer 1

a(2) = (2)^2 + 3 solve

Answer 2

possible answers can only be
4

8.667

14.667

20.667

Answer 3

Yes. My fault. Sorry.
Too early for me.

v(t) = integral of acceleration

v(t) = v(0) + (1/3) t^3 + 3t evaluated at t=2

v(2) = 12 + (8/3) + 6 = 20.667

Answer 4

thank you sooooooo much !! have a nice day !!

Answer 5

You are very welcome. Have a great day, too.
