A mechanical shovel is digging sand, each load weighs 500 kgf, The shovel lifts each load to a height of 15 m in ½ minute and then drops it. The shovel has a hole through which the sand spills, while you are lifting it, at a rate of 160 kgf / min. Calculate the work done by the shovel in lifting each load. a) 6900 kgf/m b) 6910 kgf/m c) 6995 kgf/m d) 6985 kgf/m
