How Much Work Does a Crane Do to Lift Soil?

[Iceclover]

Homework Statement

A crane lifts a 2.25x10^3 bucket containing 1.15m^3 of soil (density = 2.00x10^3kg/m^3) to a height of 7.50 m. Calculate the work the crane performs.

Homework Equations

D=m/V
W=Fd

The Attempt at a Solution

F=2n25x10^3N
d=7.50m
D=2.00x10^3 kg/m^3
V=1.15m^3
W=?

alright so I've calculated the mass the object will have and i got 2.3 x 10^3kg
Now i was just wondering if anyone could help me on where to go from here?

find the weight of the soil, add it on to the weight of the bucket and use your W=Fd equation.

how do i find the weight of the soil and the weight of the bucket?

 

[billiards]

weight=mass*g

g=acceleration due to gravity=9.81

you already know the weight of the bucket is 2.25*10³ N.

Is it N or kg? You didnt specify and its very important

 

[Iceclover]

is what in N or kg? everything is there
