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.
