If a 5 kg object is being constantly accelerated from 0m/s to 12 m/s over 16s, how much power is being applied at t= 1 s?

45 J/s.
Explanation:
see this..
{where work = force * distance}
power = ( force * distance travelled ) / time
{where force = mass * [acceleration](https://socratic.org/physics/1d-motion/acceleration)}
power = ( (mass * acceleration) * distance travelled) / time
power = ( 5 kg *
power = ( 3.75 ) * ( 192 ) / 16
power = 720 / 16
power = 45 J/s or 45 W
If object accelerates constantly than, the answer shows that 45 J ( Joule ) of energy is applied every second.
