A particle moves along a line with position $s(t)=t^2+1$, where $t$ is in seconds and $s$ is in meters. What is the particle's velocity function $v(t)$?

Question

Accepted Answer

D. $v(t)=2t$ m/s

Answer

$v(t)=t^2$ m/s

Answer

$v(t)=2t+1$ m/s

Answer

$v(t)=\dfrac{t^3}{3}+t$ m/s

Answer

$v(t)=2t$ m/s
