Question

The car moves in a straight line such that for a short time its velocity is defined by v = (3t2 + 2t) m/s, where t is in seconds. Determine its acceleration when t = 3,4 s. When t = 0, s = 0.

Answer 1

Ответ:

6

Объяснение:
v(t)=v0t+(at^2)/2

You have

v(t)=2t+3t^2

a=2*3=6 at any moment
