work = force to lift up and distance covered , it is a positive work done because direction and force are in the same direction
W= Fd
w = mgd(so you are lifting up , thats why F = mg
w = 5.0* 10^2 * 9.8 * 1.02 = + 4998kgm^2/s^2(donot forget to show positive sign)
power is = (WORK DONE)/ TIME = 1514.5454 m^2 kg/s^3
SO SIMPLEY PLUG THE VALUE OF WORK ABOVE WE DONE , AND ALSO WE have given the time
Good luck , just check out for calculation , may be i did mistake in calculating work, further question . feel free to ask me..
