A cart is released from rest at the top of a long ramp at time $t=0$ seconds and moves down the ramp at a constant acceleration rate. At a time of $t$, the cart has reached a speed of $2 { m }/{ s }$.

How fast will the cart be moving at the time of $3t$?

A

$3\ { m }/{ s }$

B

$6\ { m }/{ s }$

C

$12\ { m }/{ s }$

D

$18\ { m }/{ s }$
