The final velocity is +15.0 m/s

Explanation:

The motion of the cart is a uniformly accelerated motion (=at constant acceleration), therefore we can use the following suvat equation:

$v=u+at$

where

v is the velocity at time t

u is the initial velocity

a is the acceleration

t is the time

For the cart in this problem, we have:

u = +3.0 m/s (initial velocity)

$a=1.5 m/s^2$ (acceleration)

t = 8.0 s (time)

Substituting, we find the final velocity:

$v=3.0+(1.5)(8.0)=+15.0 m/s$
