Answer:
3750 J
Step-by-step explanation:
We are given that
Total number of cartons=10
Height of loading dock from the side walk=1.5 m
Length of ramp=10 m
Mass of each carton=25 kg
We have to find the work done by the delivery man on the cartons to move them to the loading dock.
Work done=
Where M=Total mass of object
h=Height of object above the ground
g=Acceleration due to gravity=
Total mass of cartons=M=
h=1.5 m
Substitute the values then, we get
Work done=J
Hence, the total work done by the deliverman on the cartons to move them to the loading dock=3750J
