480 N is not a power specification. It is a force specification. Newtons (N) measure force.
You need a specification of motor power (such as horsepower or Watts) to answer this question. Any motor can provide an arbitrary force by using levers or hydraulic pistons for mechanical advantage.

Show that 480 W of power is expended by a weightlifter when lifting a 60-kg barbell a vertical distance of 1.2 m in a time interval of 1.5 s.
