Power --> It is the rate of doing work i.e, Power = Work / Time

Given:

mass = 51 kg

time = 5 seconds

displacement = 5 meters

Solution:

Work = F × s

:. F = m × a

F = 51 × 10

= 510 Newton

So, the work done is:

W = 510 × 5

= 2,550 Joules

Now the power : Work/Time

=> 2,550/5

=> 510 Watt

hence, we get the required ans

Hope this helped you dear...
