In the case of work (and also energy), the standard metric unit is the Joule (abbreviated J). One Joule is equivalent to one Newton of force causing a displacement of one meter. In other words, The Joule is the unit of work (if that helped any!)

Physics

8.6 m/s

Explanation:

We can find the final velocity of the dog by using the following SUVAT equation:

v^2-u^2=2ad

where

u is the initial velocity

a is the acceleration

d is the distance covered

For the dog in the problem, we have

u = 1.5 m/s

a = 12 m/s^2

And the distance covered is

d = 3.0 m

Therefore, we can re-arrange the equation to find the final velocity, v:

$v=\sqrt{u^2+2ad}=\sqrt{1.5^2+2(12)(3.0)}=8.6 m/s$
