Aball rolls down an inclined plane such that the distance (in centimeters) that it rolls in t seconds is given by s(t) = 2t^3 + 3t^2 + 4 for 0< =t< =3 at what time is the velocity 30cm/s?
Answers: 1
for which this is equal to 30, i.e. solve
, but only one is positive and falls in the interval ![[0,3]](/tpl/images/0196/5851/a909d.png)
. So the velocity reaches 30 cm/s when
