Question
a crane lifts a metal beam with a mass of 1350 kg. Calculate the amount of work done against gravity if the beam is lifted 37.5 meters in the air.
Answers
W = F*h.
F = m*g = 1350kg * 9.8N/kg = 13,230 N.
W = 13230 * 37m = 489,510 J.
F = m*g = 1350kg * 9.8N/kg = 13,230 N.
W = 13230 * 37m = 489,510 J.
