Adeliveryman moves 10 cartons from the sidewalk, along a 10-meter ramp to a loading dock, which is 1.5 meters above the sidewalk. if each carton has a mass of 25 kg, what is the total work done by the deliveryman on the cartons to move them to the loading dock?

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

this is a very good question

step-by-step explanation:

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude
