a 1462 kilogram block was lifeted vertically at a constant velocity a distance of 0.08 x 10(to the 6th power) meters in 5minutes.
A-how much work was done?
B-what was the average power consumption in watts?
F = m*g = 1462kg * 9.8N/kg = 14,328 N.
A. Work = F*d = 14328 * 8*10^4 = 1.14621*10^9 Joules.
B. Power = W/t = 1.146*10^9 / 300s =
3.82*10^6 Joules/s. = 3.82*10^6 Watts.
